title: Rapid screening of explosives in ambient environment by aerodynamic assisted thermo desorption mass spectrometry.
abstract: Rapid, direct, and trace detection of explosives in an open environment is of particular need in homeland and/or transportation security. In this work, an aerodynamic assisted thermo desorption mass spectrometry method was developed for the direct quantitative analyses of explosives from a distance. Remote non-volatile explosive sensing was achieved for 2, 4, 6-trinitrotoluene, trinitrohexahydro-1, 3, 5-triazine, 8701 (main ingredient: RDX 98.5%), and C4 (a type of plastic explosive) with a distance of 0.65 m. Furthermore, a close to 324 cm2effective sampling area could be achieved, and the limits of detection are in the ng range. This device can be deployed in airports and subway stations for high-throughput and automatic luggage/personnel screening of prohibited articles, such as explosives and illicit drugs.
