SL/T 741-2016 in English

Scope

This standard specifies the purge and trap gas chromatography electron capture determination method for volatile halogenated hydrocarbons in water. This standard is applicable to the determination of volatile halogenated hydrocarbon organic compounds in surface water, groundwater and drinking water, including vinyl chloride, 1,1-dichloroethylene, methylene chloride, trans-1,2-dichloroethylene, chloroprene Alkene, cis-1,2-dichloroethylene, chloroform, 1,1,1-trichloroethane, 1,2-dichloroethane, carbon tetrachloride, trichloroethylene, bromodichloromethane, Determination of 17 compounds including dibromochloromethane, tetrachloroethylene, tribromomethane, 1,1,2,3-tetrachloroethane and hexafluorobutadiene. For the detection limits of each compound, please refer to Appendix A, Table A.1.
