The new technology of soluble gaseous hydrocarbons and benzene homologues in groundwater joint test

Soluble gaseous hydrocarbons and benzene homologues in groundwater is the direct indicator of hydrochemical to find oil. The direct extraction method is used in this text to test C1-C4 hydrocarbon gases and benzene homologues at the same time in the chromatography. Compared with the traditional test methods. The direct extraction has non-toxic, pollution-free, simple, rapid, high sensitivity, good repeatability, high degree of automation features, and has high practical value.
