摘　　要：采用气相色谱-质谱联用法对含叔丁基硫醇、二乙基硫醚、邻氯苯亚甲基丙二腈等多种组分的多功能控暴剂进行了定性分析,实现了各物质的完全分离和各色谱峰的归属确认。使用注射器配气法实现了标准气的配制,并采用气相色谱法对多功能控暴剂中叔丁基硫醇进行定量分析。叔丁基硫醇气体样品的质量浓度在5~1 000μg·L^(-1)内与其对应的峰高呈线性关系,进样量为1mL时,检出限(3S/N)为5μg·L^(-1)。加标回收率在97.2%~105%之间,对同一样品连续进样测定,测定值的相对标准偏差(n=6)为3.2%。The multifunctional riot control agent composed of 2-methyl-2-propanethiol,diethyl sulfide and 2-chlorobenzylidene malononitrile were analysed qualitatively by gas chromatography in hyphenation with mass spectrometry.Complete separation of the analytes was achieved and assoting of the chromatographic peaks was affirmed.2-Methyl-2-propanethiol in multifunctional riot control agent was determined by gas chromatography using syringe dispensing method in preparation of gas standards.Linear relationship between values of peak height and mass concentration of 2-methyl-2-propanethiol was kept in the range of 5-1 000μg·L^（-1）.Detection limit（3 S/N）of 5μg·L^（-1） was found when 1 mL of the sample was introduced.Values of recovery obtained by standard addition method were in the range of 97.2%-105%.By replicate introduction of a same sample,RSD（n=6）was 3.2%.
