采用平板式差分离子迁移谱( DMS)和迁移时间离子迁移谱( DTIMS)联用技术( DMS-IMS2)对典型化学战剂模拟物甲基膦酸二甲酯(DMMP)和水杨酸甲酯(MS)进行测定。实验结果表明,在载气800 mL/min, DMS射频电压1100 V条件下,DMS-IMS2在DIMS模式能够实现DMMP和MS两种化学战剂模拟物的有效识别和检测。另外,DMS-IMS2能够实现DMMP和MS正、负离子的同时检测,同时获得DMMP和MS的DMS补偿电压( CV)和IMS迁移时间( Td )的二维分离信息,为两种化学战剂模拟物的准确鉴定提供更多的信息。DMS-IMS2具有二维分析能力、可同时分析正负离子、响应速度快、体积小、功耗低等优点,在现场检测中具有广阔的应用前景。

Using a novel hybrid technology combined differential ion mobility spectrometry ( DMS) with drift time ion mobility spectrometry DMS-IMS2 , we detected the typical chemical warfare agent simulants dimethyl methylphosphonate ( DMMP ) and methyl salicylate ( MS) . With carrier gas 800 mL/min and DMS RF voltage 1100 V, the chemical warfare agents DMMP and MS could be detected and characterized by DMS-IMS2 under DIMS mode. In addition, DMS-IMS2 is capable to monitor positive and negative ions of DMMP and MS simultaneously, and provides the two-dimensional separation parameters DMS compensation voltage ( CV) and IMS drift time ( Td ) , which provides more information for the identification of two chemical warfare agents. DMS-IMS2 has potential application in on-site detection and instrument miniaturization due to its advantages including small size, low power consumption and rapid response time.
