A study was conducted to assess the applicability of double-sided adhesive coated stubs for sampling traces of TNT, RDX and PETN from suspects' hands. The double stage extraction method developed in the previous study for recovery of NG and 2,4 DNT in gunpowder residues sampled by double-sided adhesive coated stubs, was found to be applicable also for TNT, RDX and PETN. These explosives were analyzed using GC/TEA and IMS.
开展了一项研究,以评估双面粘性涂层存根用于从嫌疑人手上采集三硝基甲苯(TNT)、黑索金(RDX)和季戊四醇四硝酸酯(PETN)痕迹的适用性。之前的研究开发了一种双阶段萃取方法,用于从双面粘性涂层存根采集的火药残渣中回收硝化甘油(NG)和2,4 -二硝基甲苯(2,4 DNT),结果发现该方法也适用于TNT、RDX和PETN。使用气相色谱/热离子检测器(GC/TEA)和离子迁移谱(IMS)对这些炸药进行了分析。
