This work was followed by a method to detect TATP using ion mobility spectrometry (IMS) [19]. A year later, TATP trace detection methods for GC–MS were performed using headspace analysis [20] and Solid Phase Micro Extraction [21]. Also in 2004, a method for ...

WebEffective explosives detection requires dogs to generalize their response to untrained variations of targets that are related to those with which they were trained. Previous research suggests that dogs tend to be highly specific to their trained odors, and are sensitive to alterations in odor profiles.

WebTATP in post explosion exhibits was reported earlier to be best recovered from vapor phase. A typical procedure includes its adsorption on Amberlite XAD-7, elution with acetonitrile and analysis by GC/MS. In this work, improved recovery of TATP from the vapor phase was achieved by SPME using PDMS/DV … WebMar 26, 2008 · This report investigates the chemical degradation products of TATP after it has been treated with different acids within a sealed system over a period of 14 days. …
