Development of ion mobility spectrometry and its application for detection trace explosives

Abstract

Ion mobility spectrometry is widely used for detection of explosives in the field of airport and in the war against terror due to its satisfactory features: fast response, high sensitivity, good portability, easy operation, etc. This paper introduced the pricinple, classification and also their features of ion mobility sepctrometry; also mainly introduced recent developments of technique for detection of explosives in our laboratory including titration region-ion mobility spectrometry, new method to improve the resolution of ion mobility spectrometry and also the nonradioactive high-efficency ionization source based on VUV lamp. Finally, the development tendency and prospect of ion mobility spectrometry for detection of explosives was predicted.
