共振多光子电离探测芳香烃污染物对比实验研究

Comparison Experimental Investigation of Detection of Aromatic Molecules Pollution by Resonance Enhanced Multiphoton Ionization

本文用两种不同的方法对同期制备的不同浓度的苯、甲苯、二甲苯及其混合气和摩托车尾气三类样品分别进行了对比实验．实验验证了多光子电离所得实验数据的可靠性及其恻量精确性，同时可以看出多光子电离方法所具有的快速、实时在线和多组分同时探测的优越性．

In this paper. we made comparison experiments with benzene, toluene, xylene and their gas mixtures and motorcycle exhaust gas using HEMPI/TOFMS and GC. The experiments verified the reliablity and accuracy of the data obtained by REMPI/TOFMS, and we can see the advantage of REMPI/TOFMS in the respect of the high measurement speed, real time, on-line and multi- components detection.
