应用热脱附-气相色谱质谱法测定空气中化学毒剂模拟剂
Determination of Chemical Warfare Agents Simulants in Air by Thermal Desorption and Gas Chromatography- Mass Spectrometry
摘要
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-dimethylacet-amide, trimethyl phosphate and dimethyl methylphosphonate. The results showed that good lineari-ties 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%.关键词
