气质联用对烟气总粒相物弱极性馏分中有机物的研究

Studies of Organic Components in Total Particulate Matter of Cigarette Gas by GC/MSD

用柱色层族组成分离方法和Mass Chromatograph技术对4种兰州香烟的烟丝、总粒相物和总气相物中的弱极性馏分进行分析研究,结果表明:内在品质高的香烟,其烟丝、总粒相物和气相物中脂肪酸甲酯相对含量高,总气相物中稠环芳烃的含量低,由此可作为判识卷烟内在品质以及检测卷烟优劣的指标.

We have studied the distribution of organic components in the fraction of less polarity in total particu- late matter and cigarette gas isolated from four kinds of cigarettes made at Lanzhou. The results show that when the cigarettes are higher in quality,the contents of fatty acid methyl esters in the cigarette and in total particulate matter and cigarette gas will be higher, and the contents of polycyclic aromatic hydrocarbon in the cigarette gas will be lower. These standards can be used to examine the internal quality of the cigarettes.
