摘要
应用热解与气相色谱 质谱联用技术 (Py GC/MS) ,在无氧条件下对部分国产卷烟样品进行了热解成分分析。定性定量分析结果表明 ,该方法有较好重复性 (相对标准偏差 <3% ) ;不同卷烟样品 ,具有不同的热解成分构成 ;部分烟草香味物和有害物的含量因样品不同 ,而变化幅度较大。该方法可为推测热解机理 ,设计低害卷烟 ,选择适宜的烟草添加剂 。
Pyrolysis gas chromatography-mass spectrometry was used to analyse the pyrolysis products of some domestic brand cigarettes. And some explorations have been done on the analysis of the aroma constituents in cigarette by the application of pyrolysis method. The results obtained indicated that the components were different from the different samples, and these showed the information of interrelationship to the different tastes of the samples. The method has a good repeatability ( relative standard devariation bellow 10%). The results could supply much information in developing cigarette, selecting additives, and also for studing or addressing several areas related to pyrolysis kinetics and mechanisms.
