In this work, thermal decomposition has been used to detect explosives by IMS in positive polarity. Explosives including Pentaerythritol Tetranitrate (PETN), Cyclo-1,3,5-Trimethylene-2,4,6-Trinitramine (RDX), 2,4,6-Trinitrotoluene (TNT), 2,4-Dihydro-5-nitro-3H-1,2,4-triazol-3-one (NTO), 1,3,5,7-Tetranitro-1,3,5,7-tetrazocine (HMX), have been evaluated at temperatures between 150 and 250 degrees C in positive polarity in air. Explosives yield NO(x) which causes NO(+) peak to increase. Additional peaks may be used to identify the type of explosive. The limit of detection for RDX, HMX, PETN, NTO, and TNT were obtained to be 1, 10, 40, 1000, and 1000 ng, respectively.
在这项工作中，通过 IMS 在正极性下使用热分解来检测爆炸物。包括五硝基戊四醇（PETN）、环三亚甲基三硝胺（RDX）、2,4,6-三硝基甲苯（TNT）、2,4-二氢-5-硝基-3H-1,2,4-三唑-3-酮（NTO）、1,3,5,7-四硝基-1,3,5,7-四氮杂环辛烷（HMX）在内的爆炸物在 150 至 250 摄氏度的正极性空气中进行了评估。爆炸物产生的氮氧化物（NOx）导致 NO(+)峰增加。其他峰可用于识别爆炸物的类型。RDX、HMX、PETN、NTO 和 TNT 的检测限分别为 1、10、40、1000 和 1000ng。
