The most common ionization source for the analysis of explosives by IMS has been radioactive 63Ni, used to ionize explosive vapors. However, the health risks of 63Ni, as well as low ion signals, have led many researchers to investigate other ionization techniques for analyzing explosives. This paper presents the analysis of explosives using corona discharge ionization combined with high performance ion mobility spectrometry–mass spectrometry.
