| 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%. |
