The detection of explosives, energetic materials, and their associated compounds for security screening, demining, detection of unexploded ordnance, and pollution monitoring is an active area of research. A wide variety of detection methods and an even wider range of physical chemistry issues are involved in this very challenging area. This review focuses on techniques such as optical and mass spectrometry and chromatography for detection of trace amounts of explosives with short response times…

Detection of explosives at trace levels by laser-induced breakdown spectroscopy (LIBS)

In order to realize a compact instrument for detection of explosive at trace levels, LIBS was applied on residues from different explosives and potentially interfering materials. The residues were

Ion spectrometric detection technologies for ultra-traces of explosives: a review.

The two closely related ion spectrometric methods used in explosive analyses include mass spectrometry (MS) and ion mobility spectrometers (IMS), and the four requirements-speed, selectivity, sensitivity, and sampling-are fulfilled with both of these methods.

On-site Rapid Detection of Trace Non-volatile Inorganic Explosives by Stand-alone Ion Mobility Spectrometry via Acid-enhanced Evaporization

This work proposed a strategy for detecting trace inorganic explosives by thermal desorption ion mobility spectrometry (TD-IMS) with sample-to-sample analysis time less than 5 s based on in-situ acidification on the sampling swabs and demonstrated that this method could be easily employed in the current deployed IMS for on-site sensitive detection of either in organic explosives or organic ones.
