“…IC equipped with conductivity detection (to measure electrical conductivity between two electrodes) has been developed to detect ionic species such as chlorate, perchlorate, and inorganic nitrate [89]. Gradients in ion chromatography have been shown to be the best procedure to detect inorganic explosives [95]. In CE, contactless conductivity, or indirect UV detection are used to separate ionic species [78,96].…”

Microfluidic technology is a powerful tool to enable the rapid, accurate, and on-site analysis of forensically relevant evidence on a crime scene. This review paper provides a summary on the application of this technology in various forensic investigation fields spanning from forensic serology and human identification to discriminating and analyzing diverse classes of drugs and explosives. Each aspect is further explained by providing a short summary on general forensic workflow and investigations for body fluid identification as well as through the analysis of drugs and explosives. Microfluidic technology, including fabrication methodologies, materials, and working modules, are touched upon. Finally, the current shortcomings on the implementation of the microfluidic technology in the forensic field are discussed along with the future perspectives.

“…All of the results obtained for the mPADs correlated with previous analysis using varying analytical instrumentation. 26 Inuence of the mPAD dimensions in the reaction time The mPAD size and set up was also adjusted in order to permit faster analysis times. The mPAD size was reduced from 45 mm Â 38 mm to 24 mm Â 17 mm for future testing analysis.…”

“…Although the majority of media coverage has focussed on large-scale incidents, there has also been a rise in nuisance explosions involving smaller devices such as pipe bombs. This is particularly the case in the United States, where pipe bombs are considered to make up the vast majority of IED encounters [1,2]. These devices can be easily constructed from everyday materials, and the containment provided by the pipe can produce a large explosive effect using simple low-order explosives.…”

The investigation of explosive events requires appropriate evidential protocols to recover and preserve residues from the scene. In current protocols however, there is a lack of scientifically rigorous investigation concerning their validity. In this study, a central composite design was used to determine statistically validated optimum recovery parameters for double-base smokeless powder residues on steel, analysed using total vaporisation (TV) SPME/GC-MS. It was found that maximum recovery was obtained using isopropanol-wetted swabs stored under refrigerated conditions for a minimum period, then extracted for 15 minutes into acetone. These parameters were applied to the recovery of post-blast residues deposited on steel witness surfaces following a PVC pipe bomb detonation, resulting in detection of all target components across the majority of samples. Higher overall recoveries were obtained from plates facing the sides of the device, consistent with the point of first failure occurring in the pipe body as observed in previous studies. The methodology employed here may be readily applied to a variety of other explosive compounds, and thus assist in establishing 'best practice' procedures for explosive investigations.
