摘　　要：运用超临界CO2流体萃取与液相色谱串联质谱相结合的方法对主流烟气的四种烟草特有亚硝胺进行了萃取与分析,结果表明:在夹带剂-甲醇流量为0.2mL/min、压力为350bar、萃取温度为70℃、CO2的流量为2L/min的条件下,静态萃取20min、动态萃取30min,烟草特有亚硝胺的萃取率达95%以上。本方法实现了"萃取-分离-检测"三位一体萃取烟草特有亚硝胺的目的,为卷烟烟气中烟草特有亚硝胺的萃取及分析提供了新方法。The tobacco-specific nitrosamines in mainstream smoke of cigarettes were extracted and analyzed by the method of the supercritical fluid extraction and liquid chromatography tandem mass spectrometry in this paper.The results showed that the extraction rate of TSNAs was above 95% at the pressure of 350bar, the temperature of 70℃,the CO2 and methanolflow rate of 2L/min and 0.2mL/min,the static extraction time of 20min and the dynamic extraction time of 30min, which obtained a global method of ＂extraction- separation- detection＂ for the extraction of tobacco-specific nitrosamines.
