摘　　要：建立了同时测定化妆品中7种挥发性化合物的吹扫捕集气相色谱法(PT-GC),该方法最大的优点就是不用任何有机溶剂对样品萃取和浓缩,减少了对环境的污染,具有灵敏度高、检出限低、定量准确、操作简便等特点。结果表明:此方法有较好的重复性,相对标准偏差在6%以下;检出限为0.3056-7.1373ng/mL;7种物质的回收率在80.87%—107.15%之间。The method of purge and trap coupled to a gas chromatographic was developed and validated for the determination of volatile organic compounds in cosmetic. The method is non destructive,and avoids the use of organic solvents. The detection and quantification limit of purge and trap is low, the precision is considered adequate for low-level determination of the target analytes in the sample matrix. The precision was perfect （RSD（6%）. The detection limit was 0. 3056--7. 1373 ng/mL. The average recoveries were from 80.87% to 107.15%.
