Identification of Improvised Inorganic Explosive Devices by Analysis of Postblast Residues Using Ion Chromatography and Capillary Electrophoresis

摘要: Chemical analysis of the residues from improvised explosive devices (IEDs) has become a topical subject as result increased frequency terrorist bomb attacks. There is need to identify type device and its composition, which in turn can assist identification perpetrators. IEDs either be organic based (high explosives) or more easily produced inorganic-based low explosives. Analysis remaining after deflagration an inorganic IEDs presents several problems. A wide variety ionic species may present (such unconsumed starting products, formed part reaction) along with environmental background species. Therefore, it important that target ions used separated other sample. The instrumental techniques capillary electrophoresis (CE) ion chromatography (IC) are proving ideally suited this task. Both have fundamental advantages, CE offering highly efficient separations within short run time, IC high selectivity, sensitivity, reproducibility. In article, outline analytical methods area presented, particular focus on application IC. brief literature review published provided, information explosives, sampling techniques, portable instrumentation, recent developments.
