Samples can be introduced,into the GC using direct injection or purge-and-trap (Method 5030). Ground water,samples must be analyzed using Method 5030. A temperature program is used in the,gas chromatograph to separate the organic compounds. Detection is achieved by,a electrolytic conductivity detector (HECD).,2.2 The method provides an optional gas chromatographic column that may,be helpful in resolving the analytes from co-eluting non-target compounds and for,analyte confirmation.,3.0 INTERFERENCES,3.1 Refer to Methods 5030 and 8000.,3.2 Samples can be contaminated by diffusion of volatile organics,(particularly chlorofluorocarbons and methylene chloride) through the sample,container septum during shipment and storage. A trip blank prepared from,organic-free reagent water and carried through sampling and subsequent storage,and handling can serve as a check on such contamination.,CD-ROM 8010B - 3 Revision 2,September 1994,4.0 APPARATUS AND MATERIALS,4.1 Gas chromatograph,4.1.1 Gas chromatograph - analytical system complete with gas,chromatograph suitable for on-column injections or purge-and-trap sample,introduction and all required accessories, including detector, analytical,columns, recorder, gases, and syringes. A data system for measuring peak,heights and/or peak areas is recommended.,4.1.2 Columns,4.1.2.1 Column 1 - 8 ft x 0.1 in. ID stainless steel or,glass column packed with 1% SP-1000 on Carbopack-B 60/80 mesh or,equivalent.,4.1.2.2 Column 2 - 6 ft x 0.1 in. ID stainless steel or,glass column packed with chemically bonded n-octane on Porasil-C,100/120 mesh (Durapak) or equivalent.,4.1.3 Detector - Electrolytic conductivity (HECD).,4.2 Sample introduction apparatus, refer to Method 5030 for the,appropriate equipment for sample introduction purposes.,4.3 Syringes, 5 mL Luerlok glass hypodermic and a 5 mL, gas-tight with,shutoff valve.,4.4 Volumetric flask, Class……
