基于紫外光离子源高场不对称波形离子迁移谱的化学战剂模拟剂检测
Detection of Chemical Warfare Agent Simulants by UV Photoionization High-Field Asymmetric Ion Mobility Spectrometry
摘要
Abstract
Accurate diffusion was used to get low concentrations samples, and then the samples were detected by UV photoionization high-field asymmetric ion Mobility spectrometry ( UV-FAIMS ) . The samples were chemical warfare agent simulants ( CWAS) vapor:dimethyl methylphosphonate ( DMMP ) , dimethyl sulfoxide ( DMSO) , tributyl phosphate ( TBP ) and dimethyl sulfoxide ( DMF) . The results of FAIMS spectra data were analyzed by separation of spectra at different dispersion voltage ( DV ) and compensation voltage ( CV ) . A two-dimensional spectrum of α2 and α4 of CWAS was established. It was shown that FAIMS could identify CWAS well and have a good sensitivity. Take DMMP as a example, the detection limit was better than 0. 55 μg/L.关键词
