| Abstract: | Laser mass spectrometry is a new method for detection of environmental pollution. The features of this new method is to achieve high sensitivity, high selectivity, multicomponent, high speed and real time. The present paper gives an introduction to the systematic structure, function of every parts and key specification of the mobile laser spectometer and reports some key technological problems in the process of development and design this instrument. Detection result obtained from a real time on line monitoring of vehicle exhaust gas by the instrument are presented. |
