Abstract The detection of explosives and explosive devices based on the volatile compounds they emit is a long‐standing tool for law enforcement physical security. Toward that end, solid‐phase microextraction (SPME) combined with gas chromatography–mass spectrometry (GC–MS) has become crucial analytical identification volatiles emitted by explosives. Previous SPME studies have identified many common formulations serve as main charge in devices. However, limited research been conducted...
Explosive-detecting canines (EDCs) show high sensitivity in detecting explosives that they are trained to detect. The ability of detect explosive residues the parts per trillion level can sometimes result nuisance alerts. These alerts occur when various materials (i.e., substrates) exposed volatile organic compounds (VOCs) present mixtures, leading contamination—the unintended absorption or adsorption VOCs by substrate. Chemical constituents such as taggant, plasticizer, and residual solvent...
