卷烟抽吸过程中香线滤棒内含致香成分逐口转移的研究

Puff-by-puff Transfer Ratios of Aroma Components in Fragrance Line Filter Rod During Tobacco Smoking

为了探索香线滤棒中致香成分在卷烟燃烧过程中随主流烟气的转移情况,采用了气相色谱-质谱联用法（GC-MS）分析技术,对卷烟前7口主流烟气总粒相物中的薄荷醇及苯乙醇进行了定量分析。结果表明,试验所建立的检测方法具有较好的准确性,线性相关系数大于0.999,回收率为98%～104%。随着卷烟的抽吸口数增加,除第一口卷烟刚点燃释放量较低外,剩下6口均以一定的线性关系呈上升趋势。

To explore the transfer situation of aroma components of fragrance line filter rod in the process of burning with mainstream smoke, the menthol and phenethyl alcohol in the first 7 puffs mainstream smoke particles of tobacco was quantitatively analyzed with GC-MS analytical techniques. Results showed that, the method established had high accuracy, the linearity correlation coefficient was greater than 0.999 and the recovery ratio was between 98%～104%. As the number of puffs of tobacco increased, except for the low light emission volume of the first puff, the other six puffs were on the rise based on a linear relationship.
