摘 要:【目的】分析电加热烟草产品烟气主要成分烟碱、甘油以及1,2-丙二醇的逐口释放行为。【方法】以不同长度滤嘴中空段、聚乳酸段以及醋酸纤维段的电加热烟草产品为研究对象,检测烟气主要成分烟碱、丙二醇与甘油的烟气逐口释放量,分析烟气逐口相对释放量与逐口释放量质量分数。【结果】(1)不同滤嘴结构的烟草产品烟芯中烟碱、丙二醇与甘油的残留率和检测回收率并无明显变化。烟碱和丙二醇的回收率较高,甘油的回收率仅有72%。电加热烟草产品抽吸结束后,烟芯中烟碱和丙二醇残留率较低,甘油残留率高达55%。(2)不同滤嘴结构的各烟支样品逐口烟碱、丙二醇以及甘油的相对释放量基本相同,总体呈先升高后降低的趋势。(3)样品烟支烟气中的烟碱、丙二醇与甘油的逐口平均释放质量分数保持稳定,不同结构的滤嘴对烟气主要成分几乎没有选择性。[Objective]This study aims to investigate the puff-by-puff release laws of three main constituents(nicotine,1,2-propanediol and glycerol)in aerosol.[Methods]The electrically heated tobacco products(eHTPs)with different structured filters and lengths were taken as the research objects.The filter of eHTP is composed of hollow acetate section,polylactic acid section and acetate fiber section.By referring to the relative national and industrial standards,the puff-by-puff release laws of nicotine,1,2-propanediol and glycerol in aerosol were measured.The relative puff-by-puff release amount and the mass fraction of puff-by-puff release amount of three main constituents in aerosol were also analyzed.[Results](1)There are no significant changes in the residual rate and recovery rate of nicotine,1,2-propanediol and glycerol in tobacco materials of eHTP with different structured filters.The recovery rate of nicotine and 1,2-propanediol is relatively high,and the that of glycerol is only 72%.After tobacco products smoking,the residual rates of nicotine and 1,2-propanediol in tobacco materials of eHTP are relatively low,and the residual rate of glycerol is as high as 55%.(2)The relative release amounts of nicotine,1,2-propanediol and glycerol from each eHTP sample with different structured filters are basically the same,showing a trend of gradual increase and then decrease.(3)The average release mass fraction of nicotine,1,2-propanediol and glycerol in aerosol remain stable,and different structured filters have almost no selectivity to the main constituents in aerosol.
