Summary of Test Method3.1 Waste samp

14、les are analyzed by direct injection, or by carbon disulfide, M-Pyrol, or other suitable solvent extraction andinjection of the extract into a gas chromatograph. Detection is achieved using a detector which is specific for the neededapplication, for example, flame ionization detector (FID), electron

15、 capture detector (ECD), thermal conductivity detector (TCD),photoionization detector (PID), or mass selective detector (MSD). This test method may be expanded to utilize other detector typesnot previously mentioned.4. Significance and Use4.1 This test method is useful in identifying the major solve

16、nt constituents in hazardous waste samples. This test method isdesigned to support field or site assessments, recycling operations, plant operations, or pollution control programs.5. Interferences5.1 Interferences may be encountered from any number of organic compounds that respond in the detector.A

17、lso, closely elutingcomponents may complicate identification based solely on retention time. When these types of interferences are encountered, theanalyst must rely on other sources of information for positive identification, such as:5.1.1 Gas chromatography/mass spectrometric (GC/MS) confirmation,

18、see EPA Method 8260, direct injection technique;5.1.2 Use of confirmation column, or confirmatory detector;5.1.2.1 This method identifies one column (DB1701) and one detector (FID) and utilizes three solvent standards and one QCdaily check. Use of confirmatory columns or detectors, or both, will als

19、o require the use of the three solvent standards (see Note2, 8.1) and QC daily check, one for each confirmatory column or detector, or both.5.1.3 Use of varying temperature programs or standard comparison, or both;5.1.3.1 Use of varying analytical programs will also require the use of three solvent

20、standards and QC daily check for eachvariation.5.1.4 Sample history, for example, any information available from the waste generator; and,5.1.5 Physical characteristics, for example, flammability, specific gravity, or miscibility with water.5.2 Interferences may also be encountered from syringe carr

21、yover. Immediately following each injection, the syringe should bethoroughly rinsed with carbon disulfide, or M-Pyrol. Other solvents such as methanol may be used as rinse solvents if sample typesnecessitate their use, but be aware that carryover and possible interferences may occur if the rinse sol

22、vent is not completely cleanedfrom the syringe before reuse. Before each injection the syringe must be thoroughly rinsed with the sample to be injected, wherethe first two pumps are flushed into a separate waste receptacle.5.3 When carbon disulfide (CS2) is used to extract solids or sludges that con

23、tain significant amounts of water, low recovery ofthe water miscible solvents may result.5.4 Some grades of CS2 may contain trace amounts of benzene.5.5 M-Pyrol seems to degrade slowly with time. The low-level degradation products interfere with some late eluting compoundson some columns (approximat

24、ely five small peaks).5.6 Interference from the CS2 solvent peak may occur if using a TCD.5.7 When using a TCD, be aware that water, as well as oxygenated compounds, for example, MEK, MIBK, may suppressdetector response.2 For referencedASTM standards, visit theASTM website, www.astm.org, or contactA

35、om many vendors.8. Standard Preparation8.1 Stock Standard SolutionsStock standards are prepared from pure standard materials. It is recommended that the standardsbe prepared so that each component is 5 to 10 % by weight. The stock standards must be prepared by directly weighing eachcomponent. For ex

36、tremely volatile components, such as ether and freons, it is recommended that a new stock standard be prepareddaily or as needed. If a dilution solvent is needed when preparing the stock standards, use the same solvent used for sampleextraction or dilution in Section 7.NOTE 2Due to the incompatibili

37、ty of some standard compounds, that is, some compounds are not miscible with each other, and also because of thenumber of compounds typically looked for in a single chromatographic run, it is advisable to prepare 3 or 4 standard solutions each composed of 10 to15 compounds. A set of standard chromat

38、ograms and a retention timetable should be available for reference.8.2 Secondary Working StandardsThese are prepared from stock standard solutions using the appropriate solvent. Secondarystandards should encompass the linear range of the GC system.NOTE 3Linear response and range must be established

39、with all detectors and chromatography systems used for quantitation. All calibration andsample analysis must be done within the established linear range.8.3 Calibration Check StandardAcalibration check standard should be prepared. The standard mixture should provide a goodoverall check of the GC/det

40、ector system. The compounds should cover the major compound types, for example, alcohols,aromatics, aliphatics, ketones, and halogenates.Atypical calibration check standard flame ionization detector (FID) chromatogramis shown in Fig. 1.9. Sample Collection, Preservation, and Handling9.1 Sample colle

41、ction should be in accordance with appropriate sampling protocols.9.2 Samples should be collected in glass containers, that have tightly sealing caps. If very volatile organics are of particularinterest, the headspace in the container should be kept to a minimum.9.3 Sample Transfer ImplementsImpleme

42、nts are required to transfer portions of waste samples from the sample containers tothe laboratory containers. Liquid samples may be transferred using disposable pipets. Solids and semisolids may be transferredusing a conventional laboratory spatula.9.4 Samples shall be handled maintaining safe labo

43、ratory practices. Any samples with special hazards must be appropriatelylabeled.9.5 Unused sample material, laboratory dilutions, and waste from the samples may be regulated. Consult your specialist or theregulations, or both, for guidance in the proper handling and disposal of laboratory wastes.4 R

Procedure10.1 Sample Preparation:10.1.1 Analyze liquid matrices with relatively low viscosity using direct injection into the GC, either as received or after dilutionwith CS2, M-Pyrol, or other suitable

46、 solvent.10.1.2 Analyze solid or semisolid samples as follows:10.1.2.1 For carbon disulfide or M-Pyrol preparation, weigh 3 g of the waste sample in a 15-mL glass vial. Add 3 g of carbondisulfide or M-Pyrol to the vial and the mixture is vortexed vigorously.After allowing the solids to settle, injec

47、t the CS2 or M-Pyrolextract into the GC.10.1.2.2 Use alternate sample sizes and extraction solvent weights if necessary. Actual sample size and solvent weight must berecorded in the appropriate sample preparation log book. It is essential for accurate waste sample analysis that sample size besuffici

48、ent to ensure a representative sample. If alternate sample size or extraction solvent volumes, or both, are used, this must bereflected in the calculations under the dilution factor in Section 11.10.1.3 Multiple phases or layers are typically present in hazardous waste samples. Depending on treatmen

49、t or processrequirements, it may be necessary to analyze each phase or layer individually.10.2 Recommended GC Operating Conditions:10.2.1 For Capillary DB-1701 with FIDColumn flow rate 11.5 mL/minMake-up gas flow rate 3060 mL/minSplit flow 60 cm3/minInjector temperature 250CDetector temperature 250CAirflow (FID) Approximately 300 mL/minHydrogen flow (FID) Approximately 30 mL/minInitial oven temperature 35CInitial time 6 minLevel 1 rate 6C/minLevel 1 final value 180CLevel 2 rate 10C/minLevel 2 final value 230CRun time 40 minThreshold 4 unitsPe
