【Abstract】 In this paper, the principle and features of a new pollution monitoring method--laser mass spectrometry were described in detail. The method was used to preliminarily measure the vehicle emission, and multiphoton ionization time of flight mass spectrum of the exhaust gas of a car was obtained. The plot between the operating conditions of engine and benzene and its derivative pollutant emission concentration was detected on line.更多还原
