毛细管气相色谱法测定环境空气中的氯仿

Determination of chloroform in environmental air by capillary column GC

用活性炭采样管富集环境空气中的氯仿 ,以二硫化碳为解吸剂 ,经毛细管柱 GC/ECD测定样品中的氯仿 ,以保留时间定性 ,峰高定量。

The activated charcoal tube samplers are used to concentration chloroform in the environmental air Carbon disulfide is used as desorption agent The chloroform in the sample is determinated by capillary column GC/ECD The sample is qualitatively determinated by retention time and quantitatively determinated by peak height external standard methods
