中文摘要：
有机气溶胶非均相和多相反应是复杂的微界面过程,它涉及气体的吸附、扩散、反应和解吸,传统的化学分析仪器不能提供完整实时的微界面过程的化学反应信息.气溶胶质谱仪是近年来发展起来用于实时分析颗粒物化学组分的重要仪器,它弥补了传统化学分析仪器,如GC/MS在实时分析上的不足,为研究有机气溶胶非均相化学反应的微界面过程提供了新的方法.本文旨在介绍气溶胶质谱仪的结构及其在研究有机气溶胶环境微界面过程中的应用.
英文摘要：
The heterogeneous and muhiphase reactions of aerosols are complicated micro-interracial processes, which involve the absorption, diffusion, reaction and desorption of gases through the micro-interfaces of partieles. The traditional analytical instruments can not afford complete real-time chemical reaction information of the processes. Aerosol mass spectrometers arc newly developed instruments for real-time chemical composition analysis of aerosol particles, which overcome the disadvantages of the traditional analytical instruments such as GC/MS in the real-time analysis and offer a new method for the investigation on micro-interracial processes of organic aerosols. The goal of this paper is to introduce the aerosol mass spectrometers and their applications in the investigation on micro-interfacial processes of aerosols.
