Discrimination of new and aged post-blast explosives residues

Determination of Nanogram Microparticles from Explosives after Real Open-Air Explosions by Confocal Raman Microscopy

“…The analysis of postblast residues, which is an overwhelming challenge because of the almost completely consumption and destruction of the original explosive, the vast dispersion of postblast residues, the trace amount of those explosives residues, and the high contamination of the zone, has been quite less researched. Within the few studies focused on postblast residues analysis, most of them have been accomplished using liquid − or gas chromatography , coupled with mass spectrometry − for organic explosives and ion chromatography or capillary electrophoresis for inorganic explosive mixtures. − Nevertheless, these techniques are time and reagent consuming. They require laborious sample preparations and they are destructive.…”
