Rapid identification and desorption mechanisms of nitrogen-based explosives by ambient micro-fabricated glow discharge plasma desorption/ionization (MFGDP) mass spectrometry

Toward Locard’s Exchange Principle: Recent Developments in Forensic Trace Evidence Analysis

“…Meanwhile, infrared thermal desorption (IRTD) allowed for nanogram level detection of explosive substances and narcotics . Negative ion micro-fabricated glow discharge plasma desorption/ionization MS (NI-MFGDP-MS) was studied for nitrogen-based explosives and successfully applied to identify traces in open air …”

Recent advances in ambient mass spectrometry of trace explosives

“…Plasma-based techniques have also been widely employed for the trace detection of nitrated explosive materials, including LTP, 152 DART, 149 DBDI, 153, 154 HePI, 157 DAPCI, 155 FAPA, 156 and APGD. 158 Typically, these plasma-based ambient MS techniques are operated with helium discharge gas, however, argon, nitrogen, and air have also been demonstrated. A number of early investigations on DART, 18 DBDI, 154 and LTP 125 provided preliminary demonstrations of nitrate-based explosives detection and were followed up by more in-depth works.…”

A Multifunctional 3D Supermolecular Co Coordination Polymer With Potential for CO2 Adsorption, Antibacterial Activity, and Selective Sensing of Fe3+/Cr3+ Ions and TNP

“…Various techniques have been developed to detect Fe 3+ /Cr 3+ and TNP Pavlačka et al, 2016;Sadak et al, 2017;Tian et al, 2017;Goswami et al, 2013;Wen et al, 2002); among them, fluorescence analysis has been very popular due to its simplicity, sensitivity, fast response, economical way, low interference (Carter et al, 2014;Guo et al, 2014). Therefore the development of excellent fluorescence sensors for the sensitivity of Fe 3+ /Cr 3+ and TNP has become a focus.…”
