| Abstract: | Ion mobility spectrometry is widely used for field detection of explosives and illegal drugs due to its satisfactory features. Ionization source is the key part of ion mobility spectrometry, which is directly related to the sensitivity and selectivity. Recently, nonirradioactive ionization sources,represented by photon ionization source,have become a hot field. This paper introduces various ionization sources based on VUV lamp,especially dopant-assisted positive and negative ionization sources developed in our labrotory and their applications in detection of envoromental pollution and typical explosives. |
| Keywords: | dopant-assisted photoionizationsource ion mobility spectrometry reagent ion explosive |
