摘要
单颗粒气溶胶质谱技术起源于20世纪70年代,在近二十年得到了快速的发展。单颗粒气溶胶飞行时间质谱仪具有高时间分辨率,且同时测量大气中单个细颗粒物粒径、多种化学组分和混合状态的特点,在大气细颗粒物监测和科学研究中逐渐得到了广泛应用。本文对单颗粒气溶胶飞行时间质谱仪的发展历程进行了介绍,对目前已商品化的单颗粒气溶胶飞行时间质谱仪ATOFMS和SPAMS的原理、数据分析方法、结果输出方式以及在环境监测和研究中的主要应用进行了总结,并指出单颗粒气溶胶飞行时间质谱仪的发展方向。
The idea of single particle aerosol time-of-flight mass spectrometry was first proposed in the 1970s and then developed quickly in the most recent two decades. Because it can simultaneously provide much information including particle size distribution, composition of multiple chemical species and mixing state for each single particle with high time resolution, it has been widely applied in the area of environmental monitoring and fine particulate matter research. This review aims to provide an introduction of the development history and progress of single particle aerosol time-of-flight mass spectrometry, summarizes its principle, methods for data analysis, output of results and its applications in environmental measurement and research using two major commercialized instruments （ATOFMS and SPAMS）, and gives suggestions for future research direction.
