EXPLANATION
The Code of Federal Regulations is a codification of the general and
permanent rules published in the Federal Register by the Executive
departments and agencies of the Federal Government. The Code is divided
into 50 titles which represent broad areas subject to Federal
regulation. Each title is divided into chapters which usually bear the
name of the issuing agency. Each chapter is further subdivided into
parts covering specific regulatory areas.
Each volume of the Code is revised at least once each calendar year
and issued on a quarterly basis approximately as follows:
Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1
The appropriate revision date is printed on the cover of each
volume.
LEGAL STATUS
The contents of the Federal Register are required to be judicially
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie
evidence of the text of the original documents (44 U.S.C. 1510).
HOW TO USE THE CODE OF FEDERAL REGULATIONS
The Code of Federal Regulations is kept up to date by the individual
issues of the Federal Register. These two publications must be used
together to determine the latest version of any given rule.
To determine whether a Code volume has been amended since its
revision date (in this case, July 1, 1998), consult the ``List of CFR
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative
List of Parts Affected,'' which appears in the Reader Aids section of
the daily Federal Register. These two lists will identify the Federal
Register page number of the latest amendment of any given rule.
EFFECTIVE AND EXPIRATION DATES
Each volume of the Code contains amendments published in the Federal
Register since the last revision of that volume of the Code. Source
citations for the regulations are referred to by volume number and page
number of the Federal Register and date of publication. Publication
dates and effective dates are usually not the same and care must be
exercised by the user in determining the actual effective date. In
instances where the effective date is beyond the cut-off date for the
Code a note has been inserted to reflect the future effective date. In
those instances where a regulation published in the Federal Register
states a date certain for expiration, an appropriate note will be
inserted following the text.
OMB CONTROL NUMBERS
The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires
Federal agencies to display an OMB control number with their information
collection request.
[[Page vi]]
Many agencies have begun publishing numerous OMB control numbers as
amendments to existing regulations in the CFR. These OMB numbers are
placed as close as possible to the applicable recordkeeping or reporting
requirements.
OBSOLETE PROVISIONS
Provisions that become obsolete before the revision date stated on
the cover of each volume are not carried. Code users may find the text
of provisions in effect on a given date in the past by using the
appropriate numerical list of sections affected. For the period before
January 1, 1986, consult either the List of CFR Sections Affected, 1949-
1963, 1964-1972, or 1973-1985, published in seven separate volumes. For
the period beginning January 1, 1986, a ``List of CFR Sections
Affected'' is published at the end of each CFR volume.
INCORPORATION BY REFERENCE
What is incorporation by reference? Incorporation by reference was
established by statute and allows Federal agencies to meet the
requirement to publish regulations in the Federal Register by referring
to materials already published elsewhere. For an incorporation to be
valid, the Director of the Federal Register must approve it. The legal
effect of incorporation by reference is that the material is treated as
if it were published in full in the Federal Register (5 U.S.C. 552(a)).
This material, like any other properly issued regulation, has the force
of law.
What is a proper incorporation by reference? The Director of the
Federal Register will approve an incorporation by reference only when
the requirements of 1 CFR part 51 are met. Some of the elements on which
approval is based are:
(a) The incorporation will substantially reduce the volume of
material published in the Federal Register.
(b) The matter incorporated is in fact available to the extent
necessary to afford fairness and uniformity in the administrative
process.
(c) The incorporating document is drafted and submitted for
publication in accordance with 1 CFR part 51.
Properly approved incorporations by reference in this volume are
listed in the Finding Aids at the end of this volume.
What if the material incorporated by reference cannot be found? If
you have any problem locating or obtaining a copy of material listed in
the Finding Aids of this volume as an approved incorporation by
reference, please contact the agency that issued the regulation
containing that incorporation. If, after contacting the agency, you find
the material is not available, please notify the Director of the Federal
Register, National Archives and Records Administration, Washington DC
20408, or call (202) 523-4534.
CFR INDEXES AND TABULAR GUIDES
A subject index to the Code of Federal Regulations is contained in a
separate volume, revised annually as of January 1, entitled CFR Index
and Finding Aids. This volume contains the Parallel Table of Statutory
Authorities and Agency Rules (Table I), and Acts Requiring Publication
in the Federal Register (Table II). A list of CFR titles, chapters, and
parts and an alphabetical list of agencies publishing in the CFR are
also included in this volume.
An index to the text of ``Title 3--The President'' is carried within
that volume.
The Federal Register Index is issued monthly in cumulative form.
This index is based on a consolidation of the ``Contents'' entries in
the daily Federal Register.
[[Page vii]]
A List of CFR Sections Affected (LSA) is published monthly, keyed to
the revision dates of the 50 CFR titles.
REPUBLICATION OF MATERIAL
There are no restrictions on the republication of material appearing
in the Code of Federal Regulations.

\4\ For the determination of total metals the sample is not filtered before processing. A digestion procedure is required to solubilize suspended
material and to destroy possible organic-metal complexes. Two digestion procedures are given in ``Methods for Chemical Analysis of Water and Wastes,
1979 and 1983''. One (section 4.1.3), is a vigorous digestion using nitric acid. A less vigorous digestion using nitric and hydrochloric acids
(section 4.1.4) is preferred; however, the analyst should be cautioned that this mild digestion may not suffice for all samples types. Particularly,
if a colorimetric procedure is to be employed, it is necessary to ensure that all organo-metallic bonds be broken so that the metal is in a reactive
state. In those situations, the vigorous digestion is to be preferred making certain that at no time does the sample go to dryness. Samples containing
large amounts of organic materials may also benefit by this vigorous digestion, however, vigorous digestion with concentrated nitric acid will convert
antimony and tin to insoluble oxides and render them unavailable for analysis. Use of ICP/AES as well as determinations for certain elements such as
antimony, arsenic, the noble metals, mercury, selenium, silver, tin, and titanium require a modified sample digestion procedure and in all cases the
method write-up should be consulted for specific instructions and/or cautions.
Note to Table IB Note 4: If the digestion procedure for direct aspiration AA included in one of the other approved references is different than the
above, the EPA procedure must be used.
Dissolved metals are defined as those constituents which will pass through a 0.45 micron membrane filter. Following filtration of the sample, the
referenced procedure for total metals must be followed. Sample digestion of the filtrate for dissolved metals (or digestion of the original sample
solution for total metals) may be omitted for AA (direct aspiration or graphite furnace) and ICP analyses, provided the sample solution to be analyzed
meets the following criteria:
a. has a low COD (20)
b. is visibly transparent with a turbidity measurement of 1 NTU or less
c. is colorless with no perceptible odor, and
d. is of one liquid phase and free of particulate or suspended matter following acidification.

the nitrification inhibitor is not a procedural option, but must be included to report the CBOD5 parameter. A discharger whose permit requires
reporting the traditional BOD5 may not use a nitrification inhibitor in the procedure for reporting the results. Only when a discharger's permit
specifically states CBOD5 is required can the permittee report data using the nitrification inhibitor.

\29\ Approved methods for the analysis of silver in industrial wastewaters at concentrations of 1 mg/L and above are inadequate where silver exists as
an inorganic halide. Silver halides such as the bromide and chloride are relatively insoluble in reagents such as nitric acid but are readily soluble
in an aqueous buffer of sodium thiosulfate and sodium hydroxide to pH of 12. Therefore, for levels of silver above 1 mg/L, 20 mL of sample should be
diluted to 100 mL by adding 40 mL each of 2 M Na2S2O3 and NaOH. Standards should be prepared in the same manner. For levels of silver below 1 mg/L the
approved method is satisfactory.

\7\ Each Analyst must make an initial, one-time demonstration of their ability to generate acceptable precision and accuracy with Methods 601-603, 624,
625, 1624, and 1625 (See Appendix A of this Part 136) in accordance with procedures each in section 8.2 of each of these Methods. Additionally, each
laboratory, on an on-going basis must spike and analyze 10% (5% for Methods 624 and 625 and 100% for methods 1624 and 1625) of all samples to monitor
and evaluate laboratory data quality in accordance with sections 8.3 and 8.4 of these Methods. When the recovery of any parameter falls outside the
warning limits, the analytical results for that parameter in the unspiked sample are suspect and cannot be reported to demonstrate regulatory
compliance.

\5\ The method may be extended to include -BHC, -BHC, endosulfan I, endosulfan II, and endrin. However, when they are known to exist,
Method 608 is the preferred method.
\6\ ``Selected Analytical Methods Approved and Cited by the United States Environmental Protection Agency.'' Supplement to the Fifteenth Edition of
Standard Methods for the Examination of Water and Wastewater (1981).
\7\ Each analyst must make an initial, one-time, demonstration of their ability to generate acceptable precision and accuracy with Methods 608 and 625
(See Appendix A of this Part 136) in accordance with procedures given in section 8.2 of each of these methods. Additionally, each laboratory, on an-
going basis, must spike and analyze 10% of all samples analyzed with Method 608 or 5% of all samples analyzed with Method 625 to monitor and evaluate
laboratory data quality in accordance with Sections 8.3 and 8.4 of these methods. When the recovery of any parameter falls outside the warning limits,
the analytical results for that parameter in the unspiked sample are suspect and cannot be reported to demonstrate regulatory compliance. These
quality control requirements also apply to the Standard Methods, ASTM Methods, and other Methods cited.
Note: These warning limits are promulgated as an ``Interim final action with a request for comments.''

recommendation by the Director, Environmental Monitoring Systems
Laboratory--Cincinnati, additional alternate test procedures for
nationwide use.
(e) Sample preservation procedures, container materials, and maximum
allowable holding times for parameters cited in Tables IA, IB, IC, ID,
and IE are prescribed in Table II. Any person may apply for a variance
from the prescribed preservation techniques, container materials, and
maximum holding times applicable to samples taken from a specific
discharge. Applications for variances may be made by letters to the
Regional Administrator in the Region in which the discharge will occur.
Sufficient data should be provided to assure such variance does not
adversely affect the integrity of the sample. Such data will be
forwarded, by the Regional Administrator, to the Director of the
Environmental Monitoring Systems Laboratory--Cincinnati, Ohio for
technical review and recommendations for action on the variance
application. Upon receipt of the recommendations from the Director of
the Environmental Monitoring Systems Laboratory, the Regional
Administrator may grant a variance applicable to the specific charge to
the applicant. A decision to approve or deny a variance will be made
within 90 days of receipt of the application by the Regional
Administrator.

Table II Notes
\1\ Polyethylene (P) or glass (G). For microbiology, plastic sample containers must be made of sterilizable
materials (polypropylene or other autoclavable plastic).
2 Sample preservation should be performed immediately upon sample collection. For composite chemical samples
each aliquot should be preserved at the time of collection. When use of an automated sampler makes it
impossible to preserve each aliquot, then chemical samples may be preserved by maintaining at 4C until
compositing and sample splitting is completed.
3 When any sample is to be shipped by common carrier or sent through the United States Mails, it must comply
with the Department of Transportation Hazardous Materials Regulations (49 CFR part 172). The person offering
such material for transportation is responsible for ensuring such compliance. For the preservation
requirements of Table II, the Office of Hazardous Materials, Materials Transportation Bureau, Department of
Transportation has determined that the Hazardous Materials Regulations do not apply to the following
materials: Hydrochloric acid (HCl) in water solutions at concentrations of 0.04% by weight or less (pH about
1.96 or greater); Nitric acid (HNO3) in water solutions at concentrations of 0.15% by weight or less (pH about
1.62 or greater); Sulfuric acid (H2SO4) in water solutions at concentrations of 0.35% by weight or less (pH
about 1.15 or greater); and Sodium hydroxide (NaOH) in water solutions at concentrations of 0.080% by weight
or less (pH about 12.30 or less).
\4\ Samples should be analyzed as soon as possible after collection. The times listed are the maximum times that
samples may be held before analysis and still be considered valid. Samples may be held for longer periods only
if the permittee, or monitoring laboratory, has data on file to show that for the specific types of samples
under study, the analytes are stable for the longer time, and has received a variance from the Regional
Administrator under Sec. 136.3(e). Some samples may not be stable for the maximum time period given in the
table. A permittee, or monitoring laboratory, is obligated to hold the sample for a shorter time if knowledge
exists to show that this is necessary to maintain sample stability. See Sec. 136.3(e) for details. The term
``analyze immediately'' usually means within 15 minutes or less of sample collection.
[[Page 28]]
5 Should only be used in the presence of residual chlorine.
6 Maximum holding time is 24 hours when sulfide is present. Optionally all samples may be tested with lead
acetate paper before pH adjustments in order to determine if sulfide is present. If sulfide is present, it can
be removed by the addition of cadmium nitrate powder until a negative spot test is obtained. The sample is
filtered and then NaOH is added to pH 12.
7 Samples should be filtered immediately on-site before adding preservative for dissolved metals.
8 Guidance applies to samples to be analyzed by GC, LC, or GC/MS for specific compounds.
9 Sample receiving no pH adjustment must be analyzed within seven days of sampling.
10 The pH adjustment is not required if acrolein will not be measured. Samples for acrolein receiving no pH
adjustment must be analyzed within 3 days of sampling.
11 When the extractable analytes of concern fall within a single chemical category, the specified preservative
and maximum holding times should be observed for optimum safeguard of sample integrity. When the analytes of
concern fall within two or more chemical categories, the sample may be preserved by cooling to 4C, reducing
residual chlorine with 0.008% sodium thiosulfate, storing in the dark, and adjusting the pH to 6-9; samples
preserved in this manner may be held for seven days before extraction and for forty days after extraction.
Exceptions to this optional preservation and holding time procedure are noted in footnote 5 (re the
requirement for thiosulfate reduction of residual chlorine), and footnotes 12, 13 (re the analysis of
benzidine).
12 If 1,2-diphenylhydrazine is likely to be present, adjust the pH of the sample to 4.0\0.2 to prevent
rearrangement to benzidine.
13 Extracts may be stored up to 7 days before analysis if storage is conducted under an inert (oxidant-free)
atmosphere.
14 For the analysis of diphenylnitrosamine, add 0.008% Na2S2O3 and adjust pH to 7-10 with NaOH within 24 hours
of sampling.
15 The pH adjustment may be performed upon receipt at the laboratory and may be omitted if the samples are
extracted within 72 hours of collection. For the analysis of aldrin, add 0.008% Na2S2O3.
\16\ Sufficient ice should be placed with the samples in the shipping container to ensure that ice is still
present when the samples arrive at the laboratory. However, even if ice is present when the samples arrive, it
is necessary to immediately measure the temperature of the samples and confirm that the 4C temperature maximum
has not been exceeded. In the isolated cases where it can be documented that this holding temperature can not
be met, the permittee can be given the option of on-site testing or can request a variance. The request for a
variance should include supportive data which show that the toxicity of the effluent samples is not reduced
because of the increased holding temperature.

1.2 This is a purge and trap gas chromatographic (GC) method
applicable to the determination of the compounds listed above in
municipal and industrial discharges as provided under 40 CFR 136.1. When
this method is used to analyze unfamiliar samples for any or all of the
compounds above, compound identifications should be supported by at
least one additional qualitative technique. This method describes
analytical conditions for a second gas chromatographic column that can
be used to confirm measurements made with the primary column. Method 624
provides gas chromatograph/mass spectrometer (GC/MS) conditions
appropriate for the qualitative and quantitative confirmation of results
for most of the parameters listed above.
1.3 The method detection limit (MDL, defined in Section 12.1)
1 for each parameter is listed in Table 1. The MDL for a
specific wastewater may differ from those listed, depending upon the
nature of interferences in the sample matrix.
1.4 Any modification of this method, beyond those expressly
permitted, shall be considered as a major modification subject to
application and approval of alternate test procedures under 40 CFR 136.4
and 136.5.
1.5 This method is restricted to use by or under the supervision of
analysts experienced in the operation of a purge and trap system and a
gas chromatograph and in the interpretation of gas chromatograms. Each
analyst must demonstrate the ability to generate acceptable results with
this method using the procedure described in Section 8.2.
2. Summary of Method
2.1 An inert gas is bubbled through a 5-mL water sample contained
in a specially-designed purging chamber at ambient temperature. The
halocarbons are efficiently transferred from the aqueous phase to the
vapor phase. The vapor is swept through a sorbent trap where the
halocarbons are trapped. After purging is completed, the trap is heated
and backflushed with the inert gas to desorb the halocarbons onto a gas
chromatographic column. The gas chromatograph is temperature programmed
to separate the halocarbons which are then detected with a halide-
specific detector.2,3
2.2 The method provides an optional gas chromatographic column that
may be helpful in resolving the compounds of interest from interferences
that may occur.
3. Interferences
3.1 Impurities in the purge gas and organic compounds outgassing
from the plumbing ahead of the trap account for the majority of
contamination problems. The analytical system must be demonstrated to be
free from contamination under the conditions of the analysis by running
laboratory reagent blanks as described in Section 8.1.3. The use of non-
Teflon plastic tubing, non-Teflon thread sealants, or flow controllers
with rubber components in the purge and trap system should be avoided.
3.2 Samples can be contaminated by diffusion of volatile organics
(particularly fluorocarbons and methylene chloride) through the septum
seal ilto the sample during shipment and storage. A field reagent blank
prepared from reagent water and carried through the sampling and
handling protocol can serve as a check on such contamination.
3.3 Contamination by carry-over can occur whenever high level and
low level samples are sequentially analyzed. To reduce carry-over, the
purging device and sample syringe must be rinsed with reagent water
between sample analyses. Whenever an unusually concentrated sample is
encountered, it should be followed by an analysis of reagent water to
check for cross contamination. For samples containing large amounts of
water-soluble materials, suspended solids,
[[Page 31]]
high boiling compounds or high organohalide levels, it may be necessary
to wash out the purging device with a detergent solution, rinse it with
distilled water, and then dry it in a 105 deg.C oven between analyses.
The trap and other parts of the system are also subject to
contamination; therefore, frequent bakeout and purging of the entire
system may be required.
4. Safety
4.1 The toxicity or carcinogenicity of each reagent used in this
method has not been precisely defined; however, each chemical compound
should be treated as a potential health hazard. From this viewpoint,
exposure to these chemicals must be reduced to the lowest possible level
by whatever means available. The laboratory is responsible for
maintaining a current awareness file of OSHA regulations regarding the
safe handling of the chemicals specified in this method. A reference
file of material data handling sheets should also be made available to
all personnel involved in the chemical analysis. Additional references
to laboratory safety are available and have been identified
4-6 for the information of the analyst.
4.2 The following parameters covered by this method have been
tentatively classified as known or suspected, human or mammalian
carcinogens: carbon tetrachloride, chloroform, 1,4-dichlorobenzene, and
vinyl chloride. Primary standards of these toxic compounds should be
prepared in a hood. A NIOSH/MESA approved toxic gas respirator should be
worn when the analyst handles high concentrations of these toxic
compounds.
5. Apparatus and Materials
5.1 Sampling equipment, for discrete sampling.
5.1.1 Vial--25-mL capacity or larger, equipped with a screw cap
with a hole in the center (Pierce 13075 or equivalent). Detergent wash,
rinse with tap and distilled water, and dry at 105 deg.C before use.
5.1.2 Septum--Teflon-faced silicone (Pierce 12722 or equivalent).
Detergent wash, rinse with tap and distilled water, and dry at 105
deg.C for 1 h before use.
5.2 Purge and trap system--The purge and trap system consists of
three separate pieces of equipment: a purging device, trap, and
desorber. Several complete systems are now commercially available.
5.2.1 The purging device must be designed to accept 5-mL samples
with a water column at least 3 cm deep. The gaseous head space between
the water column and the trap must have a total volume of less than 15
mL. The purge gas must pass through the water column as finely divided
bubbles with a diameter of less than 3 mm at the origin. The purge gas
must be introduced no more than 5 mm from the base of the water column.
The purging device illustrated in Figure 1 meets these design criteria.
5.2.2 The trap must be at least 25 cm long and have an inside
diameter of at least 0.105 in. The trap must be packed to contain the
following minimum lengths of adsorbents: 1.0 cm of methyl silicone
coated packing (Section 6.3.3), 7.7 cm of 2,6-diphenylene oxide polymer
(Section 6.3.2), 7.7 cm of silica gel (Section 6.3.4), 7.7 cm of coconut
charcoal (Section 6.3.1). If it is not necessary to analyze for
dichlorodifluoromethane, the charcoal can be eliminated, and the polymer
section lengthened to 15 cm. The minimum specifications for the trap are
illustrated in Figure 2.
5.2.3 The desorber must be capable of rapidly heating the trap to
180 deg.C. The polymer section of the trap should not be heated higher
than 180 deg.C and the remaining sections should not exceed 200 deg.C.
The desorber illustrated in Figure 2 meets these design criteria.
5.2.4 The purge and trap system may be assembled as a separate unit
or be coupled to a gas chromatograph as illustrated in Figures 3 and 4.
5.3 Gas chromatograph--An analytical system complete with a
temperature programmable gas chromatograph suitable for on-column
injection and all required accessories including syringes, analytical
columns, gases, detector, and strip-chart recorder. A data system is
recommended for measuring peak areas.
5.3.1 Column 1--8 ft long x 0.1 in. ID stainless steel or glass,
packed with 1% SP-1000 on Carbopack B (60/80 mesh) or equivalent. This
column was used to develop the method performance statements in Section
12. Guidelines for the use of alternate column packings are provided in
Section 10.1.
5.3.2 Column 2--6 ft long x 0.1 in. ID stainless steel or glass,
packed with chemically bonded n-octane on Porasil-C (100/120 mesh) or
equivalent.
5.3.3 Detector--Electrolytic conductivity or microcoulometric
detector. These types of detectors have proven effective in the analysis
of wastewaters for the parameters listed in the scope (Section 1.1). The
electrolytic conductivity detector was used to develop the method
performance statements in Section 12. Guidelines for the use of
alternate detectors are provided in Section 10.1.
5.4 Syringes--5-mL glass hypodermic with Luerlok tip (two each), if
applicable to the purging device.
5.5 Micro syringes--25-L, 0.006 in. ID needle.
5.6 Syringe valve--2-way, with Luer ends (three each).
5.7 Syringe--5-mL, gas-tight with shut-off valve.
5.8 Bottle--15-mL, screw-cap, with Teflon cap liner.
[[Page 32]]
5.9 Balance--Analytical, capable of accurately weighing 0.0001 g.
6. Reagents
6.1 Reagent water--Reagent water is defined as a water in which an
interferent is not observed at the MDL of the parameters of interest.
6.1.1 Reagent water can be generated by passing tap water through a
carbon filter bed containing about 1 lb of activated carbon (Filtrasorb-
300, Calgon Corp., or equivalent).
6.1.2 A water purification system (Millipore Super-Q or equivalent)
may be used to generate reagent water.
6.1.3 Reagent water may also be prepared by boiling water for 15
min. Subsequently, while maintaining the temperature at 90+C,
bubble a contaminant-free inert gas through the water for 1 h. While
still hot, transfer the water to a narrow mouth screw-cap bottle and
seal with a Teflon-lined septum and cap.
6.2 Sodium thiosulfate--(ACS) Granular.
6.3 Trap Materials:
6.3.1 Coconut charcoal--6/10 mesh sieved to 26 mesh, Barnabey
Cheney, CA-580-26 lot M-2649 or equivalent.
6.3.2 2,6-Diphenylene oxide polymer--Tenax, (60/80 mesh),
chromatographic grade or equivalent.
6.3.3 Methyl silicone packing--3% OV-1 on Chromosorb-W (60/80 mesh)
or equivalent.
6.3.4 Silica gel--35/60 mesh, Davison, grade-15 or equivalent.
6.4 Methanol--Pesticide quality or equivalent.
6.5 Stock standard solutions--Stock standard solutions may be
prepared from pure standard materials or purchased as certified
solutions. Prepare stock standard solutions in methanol using assayed
liquids or gases as appropriate. Because of the toxicity of some of the
organohalides, primary dilutions of these materials should be prepared
in a hood. A NIOSH/MESA approved toxic gas respirator should be used
when the analyst handles high concentrations of such materials.
6.5.1 Place about 9.8 mL of methanol into a 10-mL ground glass
stoppered volumetric flask. Allow the flask to stand, unstoppered, for
about 10 min or until all alcohol wetted surfaces have dried. Weigh the
flask to the learest 0.1 mg.
6.5.2 Add the assayed reference material:
6.5.2.1 Liquid--Using a 100 L syringe, immediately add two
or more drops of assayed reference material to the flask, then reweigh.
Be sure that the drops fall directly into the alcohol without contacting
the neck of the flask.
6.5.2.2 Gases--To prepare standards for any of the six halocarbons
that boil below 30 deg. C (bromomethane, chloroethane, chloromethane,
dichlorodifluoromethane, trichlorofluoromethane, vinyl chloride), fill a
5-mL valved gas-tight syringe with the reference standard to the 5.0-mL
mark. Lower the needle to 5 mm above the methanol meniscus. Slowly
introduce the reference standard above the surface of the liquid (the
heavy gas will rapidly dissolve into the methanol).
6.5.3 Reweigh, dilute to volume, stopper, then mix by inverting the
flask several times. Calculate the concentration in g/
L from the net gain in weight. When compound purity is assayed
to be 96% or greater, the weight can be used without correction to
calculate the concentration of the stock standard. Commercially prepared
stock standards can be used at any concentration if they are certified
by the malufacturer or by an independent source.
6.5.4 Transfer the stock standard solution into a Teflon-sealed
screw-cap bottle. Store, with minimal headspace, at -10 to -20 deg.C
and protect from light.
6.5.5 Prepare fresh standards weekly for the six gases and 2-
chloroethylvinyl ether. All other standards must be replaced after one
month, or sooner if comparison with check standards indicates a problem.
6.6 Secondary dilution standards--Using stock standard solutions,
prepare secondary dilution standards in methanol that contain the
compounds of interest, either singly or mixed together. The secondary
dilution standards should be prepared at concentrations such that the
aqueous calibration standards prepared in Section 7.3.1 or 7.4.1 will
bracket the working range of the analytical system. Secondary dilution
standards should be stored with minimal headspace and should be checked
frequently for signs of degradation or evaporation, especially just
prior to preparing calibration standards from them.
6.7 Quality control check sample concentrate--See Section 8.2.1.
7. Calibration
7.1 Assemble a purge and trap system that meets the specifications
in Section 5.2. Condition the trap overnight at 180 deg.C by
backflushing with an inert gas flow of at least 20 mL/min. Condition the
trap for 10 min once daily prior to use.
7.2 Connect the purge and trap system to a gas chromatograph. The
gas chromatograph must be operated using temperature and flow rate
conditions equivalent to those given in Table 1. Calibrate the purge and
trap-gas chromatographic system using either the external standard
technique (Section 7.3) or the internal standard technique (Section
7.4).
7.3 External standard calibration procedure:
7.3.1 Prepare calibration standards at a miminum of three
concentration levels for each parameter by carefully adding 20.0
L of one or more secondary dilution standards to 100, 500, or
1000 L of reagent water. A 25-L
[[Page 33]]
syringe with a 0.006 in. ID needle should be used for this operation.
One of the external standards should be at a concentration near, but
above, the MDL (Table 1) and the other concentrations should correspond
to the expected range of concentrations found in real samples or should
define the working range of the detector. These aqueous standards can be
stored up to 24 h, if held in sealed vials with zero headspace as
described in Section 9.2. If not so stored, they must be discarded after
1 h.
7.3.2 Analyze each calibration standard according to Section 10,
and tabulate peak height or area responses versus the concentration in
the standard. The results can be used to prepare a calibration curve for
each compound. Alternatively, if the ratio of response to concentration
(calibration factor) is a constant over the working range (<10% relative
standard deviation, RSD), linearity through the origin can be assumed
and the average ratio or calibration factor can be used in place of a
calibration curve.
7.4 Internal standard calibration procedure--To use this approach,
the analyst must select one or more internal standards that are similar
in analytical behavior to the compounds of interest. The analyst must
further demonstrate that the measurement of the internal standard is not
affected by method or matrix interferences. Because of these
limitations, no internal standard can be suggested that is applicable to
all samples. The compounds recommended for use as surrogate spikes in
Section 8.7 have been used successfully as internal standards, because
of their generally unique retention times.
7.4.1 Prepare calibration standards at a minimum of three
concentration levels for each parameter of interest as described in
Section 7.3.1.
7.4.2 Prepare a spiking solution containing each of the internal
standards using the procedures described in Sections 6.5 and 6.6. It is
recommended that the secondary dilution standard be prepared at a
concentration of 15 g/mL of each internal standard compound.
The addition of 10 L of this standard to 5.0 mL of sample or
calibration standard would be equivalent to 30 g/L.
7.4.3 Analyze each calibration standard according to Section 10,
adding 10 L of internal standard spiking solution directly to
the syringe (Section 10.4). Tabulate peak height or area responses
against concentration for each compound and internal standard, and
calculate response factors (RF) for each compound using Equation 1.
[GRAPHIC] [TIFF OMITTED] TC15NO91.094
Equation 1
where:
As=Response for the parameter to be measured.
Ais=Response for the internal standard.
Cis=Concentration of the internal standard.
Cs=Concentration of the parameter to be measured.
If the RF value over the working range is a constant (<10% RSD), the RF
can be assumed to be invariant and the average RF can be used for
calculations. Alternatively, the results can be used to plot a
calibration curve of response ratios, As/Ais, vs.
RF.
7.5 The working calibration curve, calibration factor, or RF must
be verified on each working day by the measurement of a QC check sample.
7.5.1 Prepare the QC check sample as described in Section 8.2.2.
7.5.2 Analyze the QC check sample according to Section 10.
7.5.3 For each parameter, compare the response (Q) with the
corresponding calibration acceptance criteria found in Table 2. If the
responses for all parameters of interest fall within the designated
ranges, analysis of actual samples can begin. If any individual Q falls
outside the range, proceed according to Section 7.5.4.
Note: The large number of parameters in Table 2 present a
substantial probability that one or more will not meet the calibration
acceptance criteria when all parameters are analyzed.
7.5.4 Repeat the test only for those parameters that failed to meet
the calibration acceptance criteria. If the response for a parameter
does not fall within the range in this second test, a new calibration
curve, calibration factor, or RF must be prepared for that parameter
according to Section 7.3 or 7.4.
8. Quality Control
8.1 Each laboratory that uses this method is required to operate a
formal quality control program. The minimum requirements of this program
consist of an initial demonstration of laboratory capability and an
ongoing analysis of spiked samples to evaluate and document data
quality. The laboratory must maintain records to document the quality of
data that is generated. Ongoing data quality checks are compared with
established performance criteria to determine if the results of analyses
meet the performance characteristics of the method. When results of
sample spikes indicate atypical method performance, a quality control
check standard must be analyzed to confirm that the measurements were
performed in an in-control mode of operation.
8.1.1 The analyst must make an initial, one-time, demonstration of
the ability to generate acceptable accuracy and precision
[[Page 34]]
with this method. This ability is established as described in Section
8.2.
8.1.2 In recognition of advances that are occurring in
chromatography, the analyst is permitted certain options (detailed in
Section 10.1) to improve the separations or lower the cost of
measurements. Each time such a modification is made to the method, the
analyst is required to repeat the procedure in Section 8.2.
8.1.3 Each day, the analyst must analyze a reagent water blank to
demonstrate that interferences from the analytical system are under
control.
8.1.4 The laboratory must, on an ongoing basis, spike and analyze a
minimum of 10% of all samples to monitor and evaluate laboratory data
quality. This procedure is described in Section 8.3.
8.1.5 The laboratory must, on an ongoing basis, demonstrate through
the analyses of quality control check standards that the operation of
the measurement system is in control. This procedure is described in
Section 8.4. The frequency of the check standard analyses is equivalent
to 10% of all samples analyzed but may be reduced if spike recoveries
from samples (Section 8.3) meet all specified quality control criteria.
8.1.6 The laboratory must maintain performance records to document
the quality of data that is generated. This procedure is described in
Section 8.5.
8.2 To establish the ability to generate acceptable accuracy and
precision, the analyst must perform the following operations.
8.2.1 A quality control (QC) check sample concentrate is required
containing each parameter of interest at a concentration of 10
g/mL in methanol. The QC check sample concentrate must be
obtained from the U.S. Environmental Protection Agency, Environmental
Monitoring and Support Laboratory in Cincinnati, Ohio, if available. If
not available from that source, the QC check sample concentrate must be
obtained from another external source. If not available from either
source above, the QC check sample concentrate must be prepared by the
laboratory using stock standards prepared independently from those used
for calibration.
8.2.2 Prepare a QC check sample to contain 20 g/L of each
parameter by adding 200 L of QC check sample concentrate to 100
mL of reagent water.
8.2.3 Analyze four 5-mL aliquots of the well-mixed QC check sample
according to Section 10.
8.2.4 Calculate the average recovery (X) in g/L, and the
standard deviation of the recovery (s) in g/L, for each
parameter of interest using the four results.
8.2.5 For each parameter compare s and X with the corresponding
acceptance criteria for precision and accuracy, respectively, found in
Table 2. If s and X for all parameters of interest meet the acceptance
criteria, the system performance is acceptable and analysis of actual
samples can begin. If any individual s exceeds the precision limit or
any individual X falls outside the range for accuracy, then the system
performance is unacceptable for that parameter.
Note: The large number of parameters in Table 2 present a
substantial probability that one or more will fail at least one of the
acceptance criteria when all parameters are analyzed.
8.2.6 When one or more of the parameters tested fail at least one
of the acceptance criteria, the analyst must proceed according to
Section 8.2.6.1 or 8.2.6.2.
8.2.6.1 Locate and correct the source of the problem and repeat the
test for all parameters of interest beginning with Section 8.2.3.
8.2.6.2 Beginning with Section 8.2.3, repeat the test only for
those parameters that failed to meet criteria. Repeated failure,
however, will confirm a general problem with the measurement system. If
this occurs, locate and correct the source of the problem and repeat the
test for all compounds of interest beginning with Section 8.2.3.
8.3 The laboratory must, on an ongoing basis, spike at least 10% of
the samples from each sample site being monitored to assess accuracy.
For laboratories analyzing one to ten samples per month, at least one
spiked sample per month is required.
8.3.1 The concentration of the spike in the sample should be
determined as follows:
8.3.1.1 If, as in compliance monitoring, the concentration of a
specific parameter in the sample is being checked against a regulatory
concentration limit, the spike should be at that limit or 1 to 5 times
higher than the background concentration determined in Section 8.3.2,
whichever concentration would be larger.
8.3.1.2 If the concentration of a specific parameter in the sample
is not being checked against a limit specific to that parameter, the
spike should be at 20 g/L or 1 to 5 times higher than the
background concentration determined in Section 8.3.2, whichever
concentration would be larger.
8.3.2 Analyze one 5-mL sample aliquot to determine the background
concentration (B) of each parameter. If necessary, prepare a new QC
check sample concentrate (Section 8.2.1) appropriate for the background
concentrations in the sample. Spike a second 5-mL sample aliquot with 10
L of the QC check sample concentrate and analyze it to
determine the concentration after spiking (A) of each parameter.
Calculate each percent recovery (P) as 100(A-B)%/T, where T is the known
true value of the spike.
8.3.3 Compare the percent recovery (P) for each parameter with the
corresponding QC acceptance criteria found in Table 2. These
[[Page 35]]
acceptance criteria were calculated to include an allowance for error in
measurement of both the background and spike concentrations, assuming a
spike to background ratio of 5:1. This error will be accounted for to
the extent that the analyst's spike to background ratio approaches
5:1.7 If spiking was performed at a concentration lower than
20 g/L, the analyst must use either the QC acceptance criteria
in Table 2, or optional QC acceptance criteria calculated for the
specific spike concentration. To calculate optional acceptance criteria
for the recovery of a parameter: (1) Calculate accuracy (X') using the
equation in Table 3, substituting the spike concentration (T) for C; (2)
calculate overall precision (S') using the equation in Table 3,
substituting X' for X; (3) calculate the range for recovery at the spike
concentration as (100 X'/T)\2.44(100 S'/T)%.7
8.3.4 If any individual P falls outside the designated range for
recovery, that parameter has failed the acceptance criteria. A check
standard containing each parameter that failed the criteria must be
analyzed as described in Section 8.4.
8.4 If any parameter fails the acceptance criteria for recovery in
Section 8.3, a QC check standard containing each parameter that failed
must be prepared and analyzed.
Note: The frequency for the required analysis of a QC check standard
will depend upon the number of parameters being simultaneously tested,
the complexity of the sample matrix, and the performance of the
laboratory. If the entire list of parameters in Table 2 must be measured
in the sample in Section 8.3, the probability that the analysis of a QC
check standard will be required is high. In this case the QC check
standard should be routinely analyzed with the spiked sample.
8.4.1 Prepare the QC check standard by adding 10 L of QC
check sample concentrate (Section 8.2.1 or 8.3.2) to 5 mL of reagent
water. The QC check standard needs only to contain the parameters that
failed criteria in the test in Section 8.3.
8.4.2 Analyze the QC check standard to determine the concentration
measured (A) of each parameter. Calculate each percent recovery
(P
