“…Due to its ease of synthesis and the ready availability of its precursors, it has been implicated in an increasing number of explosion incidents. [3][4][5][6][7][8][9] Ethylene glycol dinitrate (EGDN) is a well-recognised explosive compound which has had a high level of historical use. [10] It is relatively rare to find traces of explosives in an everyday environment.…”

AbstractIt can be very challenging to recover explosive traces from porous surfaces, such as clothing and car seats, compared to non-porous surfaces. The contact heater has been developed as a novel instrument designed to recover explosives traces from porous surfaces. Samples are taken by heating and drawing air across a surface, with the air flowing through a sampling cartridge containing adsorbent polymer beads, which act to trap any recovered explosive material. Any collected explosive can then be eluted from this cartridge using a solvent, prior to analysis. This paper outlines work performed to evaluate the usefulness of the contact heater with regards to the recovery of explosives traces from porous materials. Ethylene glycol dinitrate (EGDN) and triacetone triperoxide (TATP) were chosen as two representative explosives for this study. Quantification was performed using GC-MS for EGDN and LC-MS/MS for TATP. Different sampling temperatures, sampling times and elution solvents were investigated. Recovery was trialled from leather, carpet and denim. Reasonable recoveries of up to 71% were obtained following optimisation. It was also possible to recover TATP from fabrics exposed to TATP vapour in a vapour-laden jar up to two hours after exposure. The contact heater therefore appears to be a very useful tool for the recovery of explosives traces from porous materials.© 2016.

“…Stambouli have demonstrated the technical feasibility of GC-MS to detect TATP lesser than nanogram level from real post-explosion debris (Stambouli et al, 2004). Also traces of explosives in water (Yinon, 1996) and TNT residues in soil (Weiss et al, 2004) have been defined.…”

In recent years, explosive materials have been widely employed for various military applications and civilian conflicts; their use for hostile purposes has increased considerably. The detection of different kind of explosive agents has become crucially important for protection of human lives, infrastructures, and properties. Moreover, both the environmental aspects such as the risk of soil and water contamination and health risks related to the release of explosive particles need to be taken into account. For these reasons, there is a growing need to develop analyzing methods which are faster and more sensitive for detecting explosives. The detection techniques of the explosive materials should ideally serve fast real-time analysis in high accuracy and resolution from a minimal quantity of explosive without involving complicated sample preparation. The performance of the in-field analysis of extremely hazardous material has to be user-friendly and safe for operators. The two closely related ion spectrometric methods used in explosive analyses include mass spectrometry (MS) and ion mobility spectrometry (IMS). The four requirements-speed, selectivity, sensitivity, and sampling-are fulfilled with both of these methods.

“…There was reported detection of triacetone triperoxide by MS in conjunction to GC [53] and LC [54]. Other methods were based on UV degradation of triacetone triperoxide explosive to the hydrogen peroxide, which was subsequently determined on the basis of the peroxidase-catalyzed oxidation of p-hydroxyphenylacetic acid to the fluorescent dimmer [55,56] or peroxidase-catalyzed oxidation of 2,2'-azino-bis(3-ethylbenzothiazoline)-6-sulfonate to green-colored radical ion [56].…”

The upsurge in terrorist activity has generated tremendous demand for innovative tools capable of detecting major industrial, military, and home-made (improvised) explosives. Fast, sensitive, and reliable detection of explosives in the field is a very important issue in nowadays. CE, especially in its miniaturized format (lab-on-a-chip), offers great possibilities to create portable, field deployable, rapidly responding, and potentially disposable devices, allowing security forces to make the important decisions regarding the safety of civilians. This article overviews the microchip and conventional capillary electrophoretic techniques for analysis of a wide variety of explosive compounds and mixtures.
