One of the significant problems in the modern world is the detection of improvised explosives made of materials synthesized at home. Such compounds include triacetone triperoxide (TATP) and hexamethylene triperoxide diamine (HMTD). An attempt was made to construct an instrument allowing for the simultaneous detection of both compounds despite the large difference of vapor pressure: very high for TATP and very low for HMTD. The developed system uses differential ion mobility spectrometry (DMS) in combination with a specially designed gas sample injection system. The created system of detectors allowed for the detection of a high concentration of TATP and a very low concentration of HMTD. TATP detection was possible despite the presence of impurities-acetone remaining from the technological process and formed as a coproduct of diacetone diperoxide (DADP) synthesis. Ammonia added to the carrier gas improved the possibility of detecting the abovementioned explosives, reducing the intensity of the acetone signal. The obtained results were then compared with the detection capabilities of drift tube ion mobility spectrometer (DT-IMS), which has not made possible such detection as DMS.
现代世界中的一个重大问题是检测由家庭合成材料制成的简易爆炸物。这类化合物包括三丙酮三过氧化物（TATP）和六亚甲基三过氧化二胺（HMTD）。尽管TATP的蒸气压非常高，而HMTD的蒸气压非常低，但人们仍尝试构建一种能够同时检测这两种化合物的仪器。所开发的系统使用差分离子迁移谱（DMS）并结合专门设计的气体样品注入系统。所创建的探测器系统能够检测高浓度的TATP和极低浓度的HMTD。尽管存在工艺过程中残留的杂质丙酮以及作为二丙酮过氧化物（DADP）合成副产物形成的丙酮，但仍有可能检测到TATP。添加到载气中的氨气提高了检测上述爆炸物的可能性，降低了丙酮信号的强度。然后将所得结果与漂移管离子迁移谱仪（DT - IMS）的检测能力进行比较，DT - IMS无法实现像DMS这样的检测。
