Abstract
Emission of fuel combustion in vehicle engines is one of the most important sources of urban environmental pollution. In this paper we present a new method for detecting trace pollution gases of vehicle emissions - laser mass spectrometry. The principles of the laser mass spectrometry is combination of resonant enhanced multiphoton ionization with flight-of-time mass spectroscopy. The experimental setup and results on the exhaust gas of a motorcycle are detailed. By excitation of 248nm KrF excimer laser, benzene and other aromatic compounds are detected in the motorcycle exhaust gases. The preliminary results of the concentration change of these compounds with speed are also presented.
