近二十年来,随着现代分离分析技术的发展,已经能够鉴定香烟烟气中近千种化学成分。这些化学成分是香烟在高温下燃烧、裂解、氧化及裂解再合成的产物。目前国内外有关香烟烟气化学成分的鉴定,多数应用GC/MS的方法。然而单从GC/MS的数据确定未知物的结构具有一定的局限性,特别是对同分异构体,尽管数据库存有标准图谱,但有时也会给出错误
Nearly two decades, with the development of modern separation and analysis technology, has been able to identify nearly a thousand kinds of chemical constituents of cigarette smoke. These chemicals are the products of combustion, pyrolysis, oxidation and pyrolysis of cigarettes at high temperatures. At present, the identification of the chemical composition of cigarette smoke at home and abroad, the majority of the application of GC / MS method. However, determining the structure of unknowns from GC / MS data alone has some limitations, especially for isomers, which sometimes give errors despite the fact that the database contains standard profiles
