沟槽滤嘴对卷烟香味物质的截留率研究

Study on the Interception Efficiency of Aromatic Substances in the Mainstream Smoke of Groove Filter

采用同时蒸馏萃取法提取卷烟主流烟气中香味物质,并应用气相色谱—质谱联用（GC-MS）的分析鉴定技术对其进行定性定量分析,研究了沟槽滤嘴对卷烟主流烟气中不同香味物质的截留率。结果表明：沟槽滤嘴对卷烟主流烟气中的香味物质具有较强的截留作用,且均有强烈的选择性;平均截留率为72.38%,单种香味物质的截留率在20.23%~94.83%之间。

The aromatic substances in mainstream cigarette smoke were extracted by using simultaneous distillation and extraction equipment and quantitatively analyzed by GC-MS. Study the interception efficiency of flavoring substances in the mainstream smoke of groove filter. The results showed that the groove filter have strong selectivity and interception efficiency of Aromatic substances in the mainstream cigarette smoke; The average interception rate come up to 72.38 % and it can be between 20.23 %~94.83 % for a single flavor of substance.
