摘要
大气颗粒物中的左旋葡聚糖是生物质燃烧的示踪物质，它极性强，可溶于水，与其它两个立体异构体同时排放，其定量分析对分析化学挑战很大。本文介绍了几种分析大气颗粒物中左旋葡聚糖及其异构体的方法，如气相色谱法、液相色谱法等，从仪器配置、样品前处理、分析条件等几个方面进行讨论，并对几种常用的方法进行了比较，对大气分析工作者进行方法选取及定量分析提供参考。
Levoglucosan is a tracer for biomass burning sources in atmosphere. It is water - soluble polar compound, emitted simultaneously with its 2 isomers, making its quantification a challenge for analytical chemistry. The review describes analytical methods on the following aspects： instrument, sample preparation and analysis conditions, comparison is carried out. It can provide references for analytical chemists on method - selection and quantification analysis.
