烟用水基胶的热裂解-气相色谱/质谱法分析

目的]建立一种烟用水基胶的热裂解分析方法。方法]对裂解温度、气相色谱柱、色谱分离条件等进行优化,并对50个烟用水基胶样品进行裂解物质的定性分析和峰面积归一化定量分析。结果]裂解温度800℃,DB-FFAP弹性石英毛细管气相色谱柱(60 m×320.0μm×0.5μm)分析效果最好;确定了18种裂解产物,不同水基胶热裂解时产生的裂解物质含量差别较大,说明不同水基胶质量存在较大差别,这些裂解物质对卷烟感官质量和卷烟危害性有影响。结论]通过使用质量较好的水基胶可以改善卷烟的感官质量和降低卷烟的危害性。

Analysis of Cigarette Water-based Adhesive by Py-GC/MS

Objective] The aim was to establish a pyrolysis method for cigarette water-based adhesive.Method] The pyrolysis temperature,GC capillary column and programmed temperature were optimized.The qualitative analysis of pyrolysis material and normalization quantitative analysis of peak area were carried out on 50 cigarette water-based adhesive samples.Result] Pyrolysing cigarette water-based adhesives at the temperature of 800 ℃ and separating by DB-FFAP column(60 m×320.0 μm×0.5 μm) was the best.Eighteen kinds of pyrolysis products were determined,the pyrolysis material content produced by different water-based adhesive was differences,which indicates that the quality of different water-based adhesive varies significantly and they have effects on cigarette sensory quality and harmfulness.Conclusion] Using high-quality water-based adhesive could improve cigarette sensory quality and decrease harmfulness of cigarette.
