AI Article Synopsis
- Aspiration ion mobility spectrometry (IMS) was successfully utilized for the first time to detect the explosive triacetone triperoxide (TATP), generated from a solid compound.
- The TATP gas was produced and analyzed using a portable chemical detection system that combined IMS and semiconductor sensors, with concentrations measured by gas chromatography-mass spectrometry (GC-MS).
- Results indicated that the IMS responses correlated with the TATP concentrations, confirming the effectiveness of IMS in monitoring this explosive in the gas phase.
Article Abstract
Aspiration ion mobility spectrometry (IMS) has been used for the first time to screen 3,3,6,6,9,9-hexamethyl-1,2,4,5,7,8-hexaoxacyclononane explosive, the most commonly known as triacetone triperoxide (TATP). Gaseous TATP was generated from synthesized solid compound, sublimed and directed to a portable chemical detection system comprised of an aspiration-type IMS detector and six semiconductor sensors. Different unknown TATP gas phase concentrations were produced and corresponding IMS and semiconductor responses were measured. The experimental concentrations were determined by gas chromatography-mass spectrometry (GC-MS). The results evidenced that the monitored compound in the gas phase was TATP. In addition, the determined TATP concentrations and corresponding IMS intensities showed that the IMS response values were proportional to the measured TATP concentrations.
