| Title | HALOGENATED VOLATILES BY GAS CHROMATOGRAPHY USINGPHOTOIONIZATION ANDELECTROLYTICCONDUCTIVITY DETECTORS IN SERIES: CAPILLARY COLUMN TECHNIQUE |
| Abstract | Method 8021 provides gas chromatographic conditions for the detection of halogenated and aromatic volatile organic compounds. Samples can be analyzed using direct injection or purge-and-trap (Method 5030). Ground water samples must be analyzed using Method 5030 (where applicable). A temperature program is used in the gas chromatograph to separate the organic compounds. Detection is achieved by a photoionization detector (PID) and an electrolytic conductivity detector (HECD) in series. |
