Laser Mass Spectrometry for Time-Resolved Multicomponent Analysis of Exhaust Gas

A new analytical method for the fast analysis of trace substances in gas mixtures that incorporates a pulsed tunable laser system and a reflectron time-of-flight mass spectrometer is described. The technique is designed for the time-resolved detection of air pollutants in the exhaust gas of motor en...

Description
Summary:A new analytical method for the fast analysis of trace substances in gas mixtures that incorporates a pulsed tunable laser system and a reflectron time-of-flight mass spectrometer is described. The technique is designed for the time-resolved detection of air pollutants in the exhaust gas of motor engines.
