| 摘 要： | 采用Tenax-TA热脱附采样管(Tube)主动采样,以热脱附仪结合气相色谱质谱(GC-MS)联用仪为分析手段,建立了空气中4种化学毒剂模拟剂(1,2-二氯乙烷、N,N-二甲基乙酰胺、磷酸三甲酯和甲基磷酸二甲酯)的快速分析方法。结果表明,4种模拟剂在1～100 ng/tube范围内线性关系良好,相关系数均大于0.99,平均加标回收率为82%～112%,检出限为0.13～0.26 ng/tube,相对标准偏差小于15%。

| Abstract: | In this paper,Tenax-TA tubes were used for air sampling with a small volume air sampler,and a gas chromatography-mass spectrometer(GC-MS) equipped with thermal desorber was adopted to analyze 4 simulant warfare agents,including 1,2-dichloroethane,N,N-dimethylacetamide,trimethyl phosphate and dimethyl methylphosphonate.The results showed that good linearities for four simulant CWAs were obtained in the range of 1-100 ng/tube with correlation coefficients(r2) more than 0.99.The average spiked recoveries were in the range of 82%-112%.The limits of detection(LODs) ranged from 0.13 ng/tube to 0.26 ng/tube,and the relative standard deviations(RSDs) were less than 15%. |
