摘　　要：介绍有机气溶胶的采集和前处理方法,通常用滤膜采集,用溶剂萃取或者热脱附法将样品净化。按照大气颗粒物中有机气溶胶的种类,总结归纳气相色谱-质谱法在分析有机气溶胶方面的应用。气相色谱-质谱法可以有效地分离分析多种有机气溶胶,包括痕量的多环芳烃及其衍生物、正构烷烃、酯类、醛酮类、酸类、醚类等。表明气相色谱-质谱法在测定大气颗粒物中的有机物方面有着很明显的优势。The collection and pretreatment methods of organic aerosols(OA)are introduced,which are usually collected by filter membrane and purified by solvent extraction or thermal desorption.According to the types of OA in atmospheric particulates,the application of GC-MS in the analysis of OA was summarized.GC-MS can effectively separate and analyze a variety of OA,including trace Polycyclic Aromatic Hydrocarbons(PAHs),normal alkane,esters,aldehydes,ketones,acids,ethers and so on.The results show that GC-MS has obvious advantages in the determination of organic compounds in atmospheric particulates.
