HJ 736-2015 in English

本标准规定了测定土壤和沉积物中挥发性卤代烃的顶空/气相色谱-质谱法。
本标准适用于土壤和沉积物中氯甲烷等35种挥发性卤代烃的测定。其他挥发性卤代烃如果通过验证也适用于本标准。

Scope

This standard specifies a headspace/gas chromatography-mass spectrometry method for the determination of volatile halogenated hydrocarbons in soils and sediments. This standard is applicable to the determination of 35 volatile halogenated hydrocarbons such as methyl chloride in soil and sediments. Other volatile halogenated hydrocarbons also apply to this standard if verified. When the sampling amount is 2 g, the method detection limit of 35 volatile halogenated hydrocarbons is 2~3 μg/kg, and the lower determination limit is 8~12 μg/kg. See Appendix A for details.
