Resonant enhanced multiphoton ionization spectroscopy with a supersonic jet is an established method for molecular science. This familiar tool has an another possibility for chemical analysis by its resonant effect; real-time, highly sensitive analysis without pretreatment. The real-time chemical analysis is demonstrated for benzene in the automobile exhaust gas. Further extension to the history analyzer for a single suspended particulate matter is also introduced briefly.
