摘　要：采用剑桥滤片捕集卷烟主流烟气粒相物中的吡啶、喹啉和苯乙烯，用甲醇溶液萃取，萃取液经0.45 μm 滤膜后，气相色谱／质谱联用（GC／MS）测定分析卷烟主流烟气粒相物中的吡啶、喹啉和苯乙烯3种半挥发性物质含量，3种物质的线性范围分别为0.6~12.0、0.2~6.0、0.1~0.8 μg／mL，检出限分别为0.54、0.03、0.03 ng／cig，相关系数（r2）达到0.995以上。

Abstract：Pyridine，quinoline and styrene in mainstream cigarette smoke were collected by Cambridge pad and extracted with CH3OH. The extract was filtered with a 0.45 μm membrane and then analyzed with GC／MS to quantify the three substances. The linear range of the method was 0.6~12.0 μg／mL，0.2~6.0 μg／mL and 0.1~0.8 μg／mL respectively. The detection limit was 0.54 ng／cig，0.03 ng／cig and 0.03 ng／cig respectively. The correlation coefficient was over 0.995.

Key words：gas chromatography／mass spectrometry；mainstream smoke；pyridine；quinoline；styrene
