8082方法

METHOD 8082POLYCHLORINATED BIPHENYLS (PCBs)BY GAS CHROMATOGRAPHY1.0SCOPE AND APPLICATION1.1Method 8082 is used to determine the concentrations of polychlorinated biphenyls (PCBs) as Aroclors or as individual PCB congeners in extracts from solid and aqueous matrices. Open-tubular, capillary columns are employed with electron capture detectors (ECD) or electrolytic conductivity detectors (ELCD). When compared to packed columns, these fused-silica, open-tubular columns offer improved resolution, better selectivity, increased sensitivity, and faster analysis. The target compounds listed below may be determined by either a single- or dual-column analysis system. The PCB congeners listed below have been tested by this method, and the method may be appropriate for additional congeners.Compound CAS Registry No.IUPAC #Aroclor 101612674-11-2-Aroclor 122111104-28-2-Aroclor 123211141-16-5-Aroclor 124253469-21-9-Aroclor 124812672-29-6-Aroclor 125411097-69-1-Aroclor 126011096-82-5-2-Chlorobiphenyl2051-60-712,3-Dichlorobiphenyl16605-91-752,2',5-Trichlorobiphenyl37680-65-2182,4',5-Trichlorobiphenyl16606-02-3312,2',3,5'-Tetrachlorobiphenyl41464-39-5442,2',5,5'-Tetrachlorobiphenyl35693-99-3522,3',4,4'-Tetrachlorobiphenyl32598-10-0662,2',3,4,5'-Pentachlorobiphenyl38380-02-8872,2',4,5,5'-Pentachlorobiphenyl37680-73-21012,3,3',4',6-Pentachlorobiphenyl38380-03-91102,2',3,4,4',5'-Hexachlorobiphenyl35065-28-21382,2',3,4,5,5'-Hexachlorobiphenyl52712-04-61412,2',3,5,5',6-Hexachlorobiphenyl52663-63-51512,2',4,4',5,5'-Hexachlorobiphenyl35065-27-11532,2',3,3',4,4',5-Heptachlorobiphenyl35065-30-61702,2',3,4,4',5,5'-Heptachlorobiphenyl35065-29-31802,2',3,4,4',5',6-Heptachlorobiphenyl52663-69-11832,2',3,4',5,5',6-Heptachlorobiphenyl52663-68-01872,2',3,3',4,4',5,5',6-Nonachlorobiphenyl40186-72-9206CD-ROM8082 - 1Revision 0December 19961.2Aroclors are multi-component mixtures. When samples contain more than one Aroclor,a higher level of analyst expertise is required to attain acceptable levels of qualitative and quantitative analysis. The same is true of Aroclors that have been subjected to environmental degradation ("weathering") or degradation by treatment technologies. Such weathered multi-component mixtures may have significant differences in peak patterns than those of Aroclor standards.1.3Quantitation of PCBs as Aroclors is appropriate for many regulatory compliance determinations, but is particularly difficult when the Aroclors have been weathered by long exposure in the environment. Therefore, this method provides procedures for the determination of selected individual PCB congeners. The 19 PCB congeners listed above have been tested by this method.1.4The PCB congener approach potentially affords greater quantitative accuracy when PCBs are known to be present. As a result, this method may be used to determine Aroclors, some PCB congeners, or "total PCBs," depending on regulatory requirements and project needs. The congener method is of particular value in determining weathered Aroclors. However, analysts should use caution when using the congener method when regulatory requirements are based on Aroclor concentrations.1.5Compound identification based on single-column analysis should be confirmed on a second column, or should be supported by at least one other qualitative technique. This method describes analytical conditions for a second gas chromatographic column that can be used to confirm the measurements made with the primary column. GC/MS Method 8270 is also recommended as a confirmation technique when sensitivity permits (Sec. 8.0).1.6This method also describes a dual-column option. The option allows a hardware configuration of two analytical columns joined to a single injection port. The option allows one injection to be used for dual-column analysis. Analysts are cautioned that the dual-column option may not be appropriate when the instrument is subject to mechanical stress, many samples are to be run in a short period, or when highly contaminated samples are analyzed.1.7The analyst must select columns, detectors and calibration procedures most appropriate for the specific analytes of interest in a study. Matrix-specific performance data must be established and the stability of the analytical system and instrument calibration must be established for each analytical matrix (e.g., hexane solutions from sample extractions, diluted oil samples, etc.). Example chromatograms and GC conditions are provided as guidance.1.8The MDLs for Aroclors vary in the range of 0.054 to 0.90 µg/L in water and 57 to 70 µg/kg in soils. Estimated quantitation limits may be determined using the data in Table 1.1.9This method is restricted to use by, or under the supervision of, analysts experienced in the use of gas chromatographs (GC) and skilled in the interpretation of gas chromatograms. Each analyst must demonstrate the ability to generate acceptable results with this method.2.0SUMMARY OF METHOD2.1 A measured volume or weight of sample (approximately 1 L for liquids, 2 g to 30 g for solids) is extracted using the appropriate matrix-specific sample extraction technique.2.2Aqueous samples are extracted at neutral pH with methylene chloride using Method 3510 (separatory funnel), Method 3520 (continuous liquid-liquid extractor), or other appropriate technique. CD-ROM8082 - 2Revision 0December 19962.3Solid samples are extracted with hexane-acetone (1:1) or methylene chloride-acetone (1:1) using Method 3540 (Soxhlet), Method 3541 (automated Soxhlet), or other appropriate technique.2.4Extracts for PCB analysis may be subjected to a sulfuric acid/potassium permanganate cleanup (Method 3665) designed specifically for these analytes. This cleanup technique will remove (destroy) many single component organochlorine or organophosphorus pesticides. Therefore, Method 8082 is not applicable to the analysis of those compounds. Instead, use Method 8081.2.5After cleanup, the extract is analyzed by injecting a 2-µL aliquot into a gas chromatograph with a narrow- or wide-bore fused silica capillary column and electron capture detector (GC/ECD).2.6The chromatographic data may be used to determine the seven Aroclors in Sec. 1.1, individual PCB congeners, or total PCBs.3.0INTERFERENCES3.1Refer to Methods 3500 (Sec. 3.0, in particular), 3600, and 8000 for a discussion of interferences.3.2Interferences co-extracted from the samples will vary considerably from matrix to matrix. While general cleanup techniques are referenced or provided as part of this method, unique samples may require additional cleanup approaches to achieve desired degrees of discrimination and quantitation. Sources of interference in this method can be grouped into three broad categories.3.2.1Contaminated solvents, reagents, or sample processing hardware.3.2.2Contaminated GC carrier gas, parts, column surfaces, or detector surfaces.3.2.3Compounds extracted from the sample matrix to which the detector will respond.3.3Interferences by phthalate esters introduced during sample preparation can pose a major problem in PCB determinations.3.3.1Common flexible plastics contain varying amounts of phthalate esters which areeasily extracted or leached from such materials during laboratory operations. Interferences from phthalate esters can best be minimized by avoiding contact with any plastic materials and checking all solvents and reagents for phthalate contamination.3.3.2Exhaustive cleanup of solvents, reagents and glassware may be required toeliminate background phthalate ester contamination.3.3.3These materials can be removed through the use of Method 3665 (sulfuricacid/permanganate cleanup).3.4Cross-contamination of clean glassware routinely occurs when plastics are handled during extraction steps, especially when solvent-wetted surfaces are handled. Glassware must be scrupulously cleaned.Clean all glassware as soon as possible after use by rinsing with the last solvent used. This should be followed by detergent washing with hot water, and rinses with tap water and organic-free CD-ROM8082 - 3Revision 0December 1996CD-ROM 8082 - 4Revision 0December 1996reagent water. Drain the glassware, and dry it in an oven at 130E C for several hours, or rinse with methanol and drain. Store dry glassware in a clean environment. NOTE:Oven-drying of glassware used for PCB analysis can increase contaminationbecause PCBs are readily volatilized in the oven and spread to other glassware.Therefore, exercise caution, and do not dry glassware from samples containinghigh concentrations of PCBs with glassware that may be used for trace analyses.3.5Elemental sulfur (S ) is readily extracted from soil samples and may cause 8chromatographic interferences in the determination of PCBs. Sulfur can be removed through the use of Method 3660.4.0APPARATUS AND MATERIALS4.1Gas chromatograph - An analytical system complete with gas chromatograph suitable for on-column and split-splitless injection and all required accessories including syringes, analytical columns, gases, electron capture detectors (ECD), and recorder/integrator or data system.4.2GC columnsThis method describes procedures for both single-column and dual-column analyses. The single-column approach involves one analysis to determine that a compound is present, followed by a second analysis to confirm the identity of the compound (Sec. 8.4 describes how GC/MS confirmation techniques may be employed). The single-column approach may employ either narrow-bore (# 0.32 mm ID) columns or wide-bore (0.53 mm ID) columns. The dual-column approach involves a single injection that is split between two columns that are mounted in a single gas chromatograph. The dual-column approach employs only wide-bore (0.53 mm ID) columns. A third alternative is to employ dual columns mounted in a single GC, but with each column connected to a separate injector and a separate detector.The columns listed in this section were the columns used to develop the method performance data. Listing these columns in this method is not intended to exclude the use of other columns that may be developed. Laboratories may use other capillary columns provided that they document method performance (e.g., chromatographic resolution, analyte breakdown, and MDLs) that equals or exceeds the performance specified in this method.4.2.1Narrow-bore columns for single-column analysis (use both columns to confirmcompound identifications unless another confirmation technique such as GC/MS is employed).Narrow bore columns should be installed in split/splitless (Grob-type) injectors.4.2.1.130 m x 0.25 or 0.32 mm ID fused silica capillary column chemicallybonded with SE-54 (DB-5 or equivalent), 1 µm film thickness.4.2.1.230 m x 0.25 mm ID fused silica capillary column chemically bonded with35 percent phenyl methylpolysiloxane (DB-608, SPB-608, or equivalent), 2.5 µm coatingthickness, 1 µm film thickness.4.2.2Wide-bore columns for single-column analysis (use two of the three columnslisted to confirm compound identifications unless another confirmation technique such as GC/MS is employed).

Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination.NOTE:Store the standard solutions (stock, composite, calibration, internal, and surrogate standards) at 4E C in polytetrafluoroethylene (PTFE)-sealed containers CD-ROM8082 - 5Revision 0December 1996CD-ROM 8082 - 6Revision 0December 1996in the dark. When a lot of standards is prepared, it is recommended that aliquotsof that lot be stored in individual small vials. All stock standard solutions mustbe replaced after one year or sooner if routine QC (Sec. 8.0) indicates a problem.All other standard solutions must be replaced after six months or sooner if routineQC (Sec. 8.0) indicates a problem.5.2Sample extracts prepared by Methods 3510, 3520, 3540, 3541, 3545, or 3550 need to undergo a solvent exchange step prior to analysis. The following solvents are necessary for dilution of sample extracts. All solvent lots should be pesticide quality or equivalent and should be determined to be phthalate-free.5.2.1n-Hexane, C H 6145.2.2Isooctane, (CH )CCH CH(CH )332325.3The following solvents may be necessary for the preparation of standards.

Dissolve the compound in isooctane or hexane and dilute to volume in a 10-mL volumetric flask. If compound purity is 96 percent or greater, the weight may be used without correction to calculate the concentration of the stock standard solution.5.5.2Commercially-prepared stock standard solutions may be used at any concentration if they are certified by the manufacturer or by an independent source.5.6Calibration standards for Aroclors5.6.1 A standard containing a mixture of Aroclor 1016 and Aroclor 1260 will includemany of the peaks represented in the other five Aroclor mixtures. As a result, a multi-point initial calibration employing a mixture of Aroclors 1016 and 1260 at five concentrations should be sufficient to demonstrate the linearity of the detector response without the necessity of performing initial calibrations for each of the seven Aroclors. In addition, such a mixture can be used as a standard to demonstrate that a sample does not contain peaks that represent any one of the Aroclors. This standard can also be used to determine the concentrations of either Aroclor 1016 or Aroclor 1260, should they be present in a sample. Prepare a minimum of five calibration standards containing equal concentrations of both Aroclor 1016 and Aroclor 1260by dilution of the stock standard with isooctane or hexane. The concentrations should correspond to the expected range of concentrations found in real samples and should bracket the linear range of the detector.5.6.2Single standards of each of the other five Aroclors are required to aid the analystin pattern recognition. Assuming that the Aroclor 1016/1260 standards described in Sec. 5.6.1 have been used to demonstrate the linearity of the detector, these single standards of the remaining five Aroclors are also used to determine the calibration factor for each Aroclor.Prepare a standard for each of the other Aroclors. The concentrations should correspond to the mid-point of the linear range of the detector.5.7Calibration standards for PCB congeners5.7.1If results are to be determined for individual PCB congeners, then standards forthe pure congeners must be prepared. The table in Sec. 1.1 lists 19 PCB congeners that have been tested by this method along with the IUPAC numbers designating these congeners. This procedure may be appropriate for other congeners as well.5.7.2Stock standards may be prepared in a fashion similar to that described for theAroclor standards, or may be purchased as commercially-prepared solutions. Stock standards should be used to prepare a minimum of five concentrations by dilution of the stock standard with isooctane or hexane. The concentrations should correspond to the expected range of concentrations found in real samples and should bracket the linear range of the detector.5.8Internal standard5.8.1When PCB congeners are to be determined, the use of an internal standard ishighly recommended. Decachlorobiphenyl may be used as an internal standard, added to each sample extract prior to analysis, and included in each of the initial calibration standards.5.8.2When PCBs are to be determined as Aroclors, an internal standard is not used,and decachlorobiphenyl is employed as a surrogate (see Sec. 5.8).5.9Surrogate standards5.9.1When PCBs are to be determined as Aroclors, decachlorobiphenyl is used as asurrogate, and is added to each sample prior to extraction. Prepare a solution of decachlorobiphenyl at a concentration of 5 mg/L in acetone.5.9.2When PCB congeners are to be determined, decachlorobiphenyl is recommendedfor use as an internal standard, and therefore, cannot also be used as a surrogate. Therefore, tetrachloro-meta-xylene may be used as a surrogate for PCB congener analysis. Prepare a solution of tetrachloro-meta-xylene at a concentration of 5 mg/L in acetone.6.0SAMPLE COLLECTION, PRESERVATION, AND HANDLING6.1See Chapter Four, Organic Analytes for sample collection and preservation instructions.6.2Extracts must be stored under refrigeration in the dark and analyzed within 40 days of extraction.CD-ROM8082 - 7Revision 0December 19967.0PROCEDURE7.1Sample extraction7.1.1Refer to Chapter Two and Method 3500 for guidance in choosing the appropriateextraction procedure. In general, water samples are extracted at a neutral pH with methylene chloride using a separatory funnel (Method 3510) or a continuous liquid-liquid extractor (Method 3520) or other appropriate procedure. Solid samples are extracted with hexane-acetone (1:1) or methylene chloride-acetone (1:1) using one of the Soxhlet extraction (Method 3540 or 3541) procedures, ultrasonic extraction (Method 3550), or other appropriate procedure.NOTE:Use of hexane-acetone generally reduces the amount of interferences that are extracted and improves signal-to-noise.7.1.2Reference materials, field-contaminated samples, or spiked samples should beused to verify the applicability of the selected extraction technique to each new sample type.Such samples should contain or be spiked with the compounds of interest in order to determine the percent recovery and the limit of detection for that sample type (see Chapter One). When other materials are not available and spiked samples are used, they should be spiked with the analytes of interest, either specific Aroclors or PCB congeners. When the presence of specific Aroclors is not anticipated, the Aroclor 1016/1260 mixture may be an appropriate choice for spiking. See Methods 3500 and 8000 for guidance on demonstration of initial method proficiency as well as guidance on matrix spikes for routine sample analysis.7.2Extract cleanupRefer to Methods 3660 and 3665 for information on extract cleanup.7.3GC conditionsThis method allows the analyst to choose between a single-column or a dual-column configuration in the injector port. Either wide- or narrow-bore columns may be used. See Sec.7.7 for information on techniques for making positive identifications of multi-componentanalytes.7.3.1Single-column analysisThis capillary GC/ECD method allows the analyst the option of using 0.25-0.32 mm ID capillary columns (narrow-bore) or 0.53 mm ID capillary columns (wide-bore). The use of narrow-bore (0.25-0.32 mm ID) columns is recommended when the analyst requires greater chromatographic resolution. Use of narrow-bore columns is suitable for relatively clean samples or for extracts that have been prepared with one or more of the clean-up options referenced in the method. Wide-bore columns (0.53 mm ID) are suitable for more complex environmental and waste matrices.7.3.2Dual-column analysisThe dual-column/dual-detector approach involves the use of two 30 m x 0.53 mm ID fused-silica open-tubular columns of different polarities, thus different selectivities towards the target compounds. The columns are connected to an injection tee and ECD detectors. CD-ROM8082 - 8Revision 0December 19967.3.3GC temperature programs and flow rates7.3.3.1Table 2 lists GC operating conditions for the analysis of PCBs asAroclors for single-column analysis, using either narrow-bore or wide-bore capillarycolumns. Table 3 lists GC operating conditions for the dual-column analysis. Use theconditions in these tables as guidance and establish the GC temperature program andflow rate necessary to separate the analytes of interest.7.3.3.2When determining PCBs as congeners, difficulties may be encounteredwith coelution of congener 153 and other sample components. When determining PCBsas Aroclors, chromatographic conditions should be adjusted to give adequate separationof the characteristic peaks in each Aroclor (see Sec. 7.4.6).7.3.3.3Tables 4 and 5 summarize the retention times of up to 73 Aroclor peaksdetermined during dual-column analysis using the operating conditions listed in Table 2.These retention times are provided as guidance as to what may be achieved using theGC columns, temperature programs, and flow rates described in this method. Note thatthe peak numbers used in these tables are not the IUPAC congener numbers, butrepresent the elution order of the peaks on these GC columns.7.3.3.4Once established, the same operating conditions must be used for theanalysis of samples and standards.7.4Calibration7.4.1Prepare calibration standards as described in Sec. 5.0. Refer to Method 8000(Sec. 7.0) for proper calibration techniques for both initial calibration and calibration verification.When PCBs are to be determined as congeners, the use of internal standard calibration is highly recommended. Therefore, the calibration standards must contain the internal standard (see Sec. 5.7) at the same concentration as the sample extracts. When PCBs are to be determined as Aroclors, external standard calibration should be used.NOTE:Because of the sensitivity of the electron capture detector, the injection port and column should always be cleaned prior to performing the initialcalibration.7.4.2When PCBs are to be quantitatively determined as congeners, an initial five-pointcalibration must be performed that includes standards for all the target analytes (congeners).7.4.3When PCBs are to be quantitatively determined as Aroclors, the initial calibrationconsists of two parts, described below.7.4.3.1 As noted in Sec. 5.6.1, a standard containing a mixture of Aroclor 1016and Aroclor 1260 will include many of the peaks represented in the other five Aroclormixtures. Thus, such a standard may be used to demonstrate the linearity of thedetector and that a sample does not contain peaks that represent any one of theAroclors. This standard can also be used to determine the concentrations of eitherAroclor 1016 or Aroclor 1260, should they be present in a sample. Therefore, an initialfive-point calibration is performed using the mixture of Aroclors 1016 and 1260 describedin Sec. 5.6.1.CD-ROM8082 - 9Revision 0December 1996RF 'A s ×C isA is ×C sCD-ROM 8082 - 10Revision 0December 19967.4.3.2Standards of the other five Aroclors are necessary for patternrecognition. These standards are also used to determine a single-point calibration factorfor each Aroclor, assuming that the Aroclor 1016/1260 mixture in Sec. 7.3.4.1 has beenused to describe the detector response. The standards for these five Aroclors shouldbe analyzed before the analysis of any samples, and may be analyzed before or after theanalysis of the five 1016/1260 standards in Sec. 7.3.4.1.7.4.3.3In situations where only a few Aroclors are of interest for a specificproject, the analyst may employ a five-point initial calibration of each of the Aroclors ofinterest (e.g., five standards of Aroclor 1232 if this Aroclor is of concern) and not use the1016/1260 mixture described in Sec. 7.4.3.1 or the pattern recognition standardsdescribed in 7.4.3.2.7.4.4Establish the GC operating conditions appropriate for the configuration (single-column or dual column, Sec. 7.3). Optimize the instrumental conditions for resolution of the target compounds and sensitivity. A final temperature of 240-270E C may be required to elute decachlorobiphenyl. Use of injector pressure programming will improve the chromatography of late eluting peaks.NOTE:Once established, the same operating conditions must be used for bothcalibrations and sample analyses.7.4.5 A 2-µL injection of each calibration standard is recommended. Other injectionvolumes may be employed, provided that the analyst can demonstrate adequate sensitivity for the compounds of interest.7.4.6Record the peak area (or height) for each congener or each characteristic Aroclorpeak to be used for quantitation.7.4.6.1 A minimum of 3 peaks must be chosen for each Aroclor, and preferably5 peaks. The peaks must be characteristic of the Aroclor in question. Choose peaks inthe Aroclor standards that are at least 25% of the height of the largest Aroclor peak. Foreach Aroclor, the set of 3 to 5 peaks should include at least one peak that is unique tothat Aroclor. Use at least five peaks for the Aroclor 1016/1260 mixture, none of whichshould be found in both of these Aroclors.7.4.6.2Late-eluting Aroclor peaks are generally the most stable in theenvironment. Table 6 lists diagnostic peaks in each Aroclor, along with their retentiontimes on two GC columns suitable for single-column analysis. Table 7 lists 13 specificPCB congeners found in Aroclor mixtures. Table 8 lists PCB congeners withcorresponding retention times on a DB-5 wide-bore GC column. Use these tables asguidance in choosing the appropriate peaks.7.4.7When determining PCB congeners by the internal standard procedure, calculatethe response factor (RF) for each congener in the calibration standards relative to the internal standard, decachlorobiphenyl, using the equation that follows.where:。
