为了简单、灵敏地测定卷烟主流烟气中的氯乙烯,使用剑桥滤片捕集主流烟气粒相物,两个串联的吸收瓶(甲醇溶液作为吸收液)在低温冷肼条件下捕集主流烟气气相物,采用气相色谱-质谱联用仪(G C/M S)分析主流烟气气相物中氯乙烯的含量,并测定了23种国内外不同焦油量卷烟主流烟气中的氯乙烯。结果表明:①该方法的检测限为2.0 ng/支,回收率在95.0%~97.4%之间,日内精密度小于6%,日间精密度小于8%。②测定的23种国内外不同焦油量卷烟主流烟气氯乙烯的释放量范围为20.0~74.8 ng/支。该方法简单、快速、准确,适合于卷烟烟气中氯乙烯的分析。
為瞭簡單、靈敏地測定捲煙主流煙氣中的氯乙烯,使用劍橋濾片捕集主流煙氣粒相物,兩箇串聯的吸收瓶(甲醇溶液作為吸收液)在低溫冷肼條件下捕集主流煙氣氣相物,採用氣相色譜-質譜聯用儀(G C/M S)分析主流煙氣氣相物中氯乙烯的含量,併測定瞭23種國內外不同焦油量捲煙主流煙氣中的氯乙烯。結果錶明:①該方法的檢測限為2.0 ng/支,迴收率在95.0%~97.4%之間,日內精密度小于6%,日間精密度小于8%。②測定的23種國內外不同焦油量捲煙主流煙氣氯乙烯的釋放量範圍為20.0~74.8 ng/支。該方法簡單、快速、準確,適閤于捲煙煙氣中氯乙烯的分析。

For simply and sensitively determining the vinyl chloride in mainstream cigarette smoke, a gas chromatography-mass spectrometry (GC/MS) method was developed, where the particulate matter in mainstream smoke was trapped with Cambridge filter pads and gas phase cold trapped with two absorption bottle in series (methanol solution as absorbing liquid). The vinyl chloride contents in gas phase of mainstream smoke of 23 domestic and imported cigarettes with different tar deliveries were determined by the developed method. The results showed that: 1) The detection limit of vinyl chloride was 2.0 ng/cig. and the recovery ranged from 95.0% to 97.4%. The intra-day and inter-day precisions were less than 6% and 8%, respectively. 2) The vinyl chloride contents in mainstream smoke of the 23 cigarettes ranged from 20.0 to 74.8 ng/cig. This method is simple, rapid, accurate and suitable for the determination of vinyl chloride in cigarette smoke.
