| 摘 要： | 挥发性羰基化合物和苯是卷烟烟气中重要的有害物质,为此建立了P&T-GC法测定卷烟样品主流烟气中的乙醛、丙醛、丁醛、丙酮、2-丁酮和苯.该方法不用2,4-二硝基苯肼(DNPH)衍生化,不用有机溶剂萃取和浓缩,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:方法有较好的重复性,相对标准偏差在5.39%以下;检出限为0.85 ng/支～6.55 ng/支;6种物质的回收率在89.22%～98.21%之间. |

| Abstract: | Volatile carbonyls and benzene are possible sources of carcinogenicity in cigarette smoke.So the analytical method of acetaldehyde,propionaldehyde,butyraldehyde,acetone,2-butanone and benzene in mainstream smoke of cigarette samples has been established by purge and trap-gas chromatography.The compounds can be extracted and concentrated without derivation with 2,4-dinitrophenylhydrazine and organic solvent being involved.The method was with high sensitivity,low detection limit,accurate quantification,and si... |
