| 摘 要：采用劍橋濾片捕集卷煙主流煙氣粒相物中的吡啶、喹啉和苯乙烯，用甲醇溶液萃取，萃取液經(jīng)0.45 μm 濾膜后，氣相色譜／質(zhì)譜聯(lián)用（GC／MS）測定分析卷煙主流煙氣粒相物中的吡啶、喹啉和苯乙烯3種半揮發(fā)性物質(zhì)含量，3種物質(zhì)的線(xiàn)性范圍分別為0.6~12.0、0.2~6.0、0.1~0.8 μg／mL，檢出限分別為0.54、0.03、0.03 ng／cig，相關(guān)系數（r2）達到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. |
