加热烟草制品(HTPs)气溶胶成分的MD-GC/MS分析

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

【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。

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.
