英文摘要: 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 (T-d), 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.
