- Warning: The volatile halogenated hydrocarbon standard sample used in this method is harmful to human health. Protective equipment should be worn as required during operation and avoid contact with skin and clothing. This standard specifies a headspace gas chromatography method for the determination of volatile halogenated hydrocarbons in water. This standard is applicable to the determination of volatile halogenated hydrocarbons in surface water, groundwater, drinking water, seawater, industrial wastewater and domestic sewage. Specific components include 1,1-dichloroethylene, dichloromethane, trans-1,2-dichloroethylene, chloroprene, cis-1,2-dichloroethylene, chloroform, tetrachloride 14 types of carbon, 1,2-dichloroethane, trichloroethylene, bromodichloromethane, tetrachloroethylene, dibromochloromethane, tribromomethane, and hexachlorobutadiene. After other volatile halogenated hydrocarbons pass verification, this method can also be used for determination. When the headspace bottle is 22ml and the sampling volume is 10.0ml, the method detection limit of the above target compound is 0.02~6.13μg/L, and the lower limit of determination is 0.08~24.5μg/L. See Appendix A for details.
