摘　　要：建立了一种收集检测卷烟主流烟气中吡啶、喹啉和苯乙烯的方法,以甲醇(CH3OH)溶液为吸收液,直接收集吸烟机抽吸的卷烟主流烟气,采用[BMIM]PF6离子液体萃取富集,气相色谱-质谱联用(GC/MS)技术定量分析卷烟主流烟气中的吡啶、喹啉和苯乙烯3种半挥发性物质,测定过程简便快速,结果准确可靠。本方法的线性关系良好,相关系数(r2)大于0.9995,吡啶、苯乙烯和喹啉的检出限分别为24.9,9.34和4.05ng/cig(每支烟),相对标准偏差(RSD)小于6.0%,加标回收率在90.6%～107.4%之间。A method was developed for the collection and determination of pyridine, quinoline and styrene in mainstream tobacco smoke. The mainstream smoke was direct trapped with 50% methanol solution from smoking machine, then extracted and concentrated by 1-butyl-3-methylimidazolium hexafluorophosphate （[BMIM]PF6）, and analyzed with GC/MS. The established method was stable and precise and the results were accurate and credible. Good linear relations were observed with a correlation coefficient over 0. 9995. The detection limits were 24.9, 9.34 and 4.05 ng/cig for pyri- dine, styrene and quinoline respectively, the relative standard deviations were less than 6.0 %, and the recoveries were found in the range from 90.6% to 107.4% .
