加热烟草制品(HTPs)气溶胶成分的MD-GC/MS分析

  目的  了解加热烟草制品（HTPs）气溶胶成分特点。  方法  采用中心切割二维气相色谱-质谱法，对17个典型的HTPs气溶胶成分进行了分析。  结果  （1）HTPs气溶胶的主要成分与普通卷烟烟气相近，但释放量较低，其中66.7%的成分种类在HTPs气溶胶中的每口释放量小于卷烟烟气释放量的10%；（2）HTPs气溶胶中占比最高的成分为甘油（35.8%），烟碱（25.7%），1, 2-丙二醇（10.8%），乙酸（3.1%），糠醛（3.1%）等；苯甲醇、苯乙醇、茄酮、新植二烯等成分释放量与卷烟烟气较为接近；（3）不同种类HTPs气溶胶主要成分基本一致，但含氧裂解产物和酚类物质的释放量差别较大。 

Composition analysis of heated tobacco products (HTPs) aerosol by MDGC/MS

In order to investigate the chemical composition of heated tobacco products (HTPs) aerosol, a total of 90 chemical compositions such as phenols, organic nitrogen compounds, oxygenated pyrolysis products, acids and alkenes from 17 typical HTPs were analyzed by heart-cutting two-dimensional gas chromatography-mass spectrometry. Results showed that: (1) The main component of HTPs aerosol is close to that of ordinary cigarette smoke, but the release amount is significantly lower, and the release amount per puff of 66.7% of the component types in HTPs aerosols less than 10% of the ordinary cigarette release amount; (2) The components with higher proportions of HTPs aerosol are glycerin (35.8%), nicotine (25.7%), 1, 2-propanediol (10.8%), acetic acid (3.1%), furfural (3.1%); the release amount of benzyl alcohol, phenethyl alcohol, solanone, and neophytadiene is close to that of cigarette smoke; (3) The main components in Different types of HTPs aerosols are basically the same, but the release amounts of oxygenated pyrolysis products and phenolic materials are quite different.
