摘　　要：提出了吹扫捕集-气相色谱法测定卷烟主流烟气中挥发酚的分析方法，使间甲酚和对甲酚能分离并准确定量。在0．4-200．0mg·L-1范围内各成分的峰面积与其浓度之间呈线性关系，方法的检出限（3S／N）为1．8～4．2ng／支；样品的加标回收率为97．9％-101．9％；相对标准偏差（n=6）在2．04％～4．52％之间。Purge and trap technique was applied in the GC determination of volatile phenols in cigarette smoke, m-cresol and p-cresol in the smoke were successfuUy separated and accurately determined by the proposed method. Linear relationships between values of peak area and concentration of the 5 phenols determined were kept all in the range of 0. 4--200. 0 mg · L-1. Detection limits （3S/N） found for the phenols were in the range from 1.8 ng to 4. 2 ng per each cigarette. Recovery and precision were tested, giving values of recovery in the range of 97. 9%--101.9%, and values of RSD＇s （n=6） in the range from 2. 04% to 4. 52%.
