Characterization of physical properties of aerosol from electrically heated cigarette

摘要: 收集市场上5个品牌的20个电加热卷烟样品,对其总释放气溶胶和逐口释放气溶胶的物理特性(粒数浓度、粒数中值粒径和体积浓度)进行表征及对比分析。结果表明:1)电加热卷烟样品总释放气溶胶的粒数浓度主要在109个/cm3的量级,体积浓度在105μm3/cm3的量级,粒径分布轮廓为单峰分布或双峰分布,粒数中值粒径主要集中在30~60 nm范围内;2)不同品牌电加热卷烟总释放和逐口释放气溶胶物理特性的均存在明显差异,同一电加热卷烟样品逐口释放气溶胶的粒数浓度、粒数中值粒径和体积浓度均呈现出一定的逐口不稳定性。Abstract: In order to study the physical properties of aerosol from electrically heated tobacco products (HTPs) and to provide the basis for the inhalation safety evaluation of aerosol from HTPs, [BP)]20 kinds of electrically heated cigarettes from 5 brands in the market were collected to characterize and compare the physical properties (number concentration, count median diameter and volume concentration) of total and puff-by-puff released aerosol. The results showed that the particle number concentration of the total aerosol released from the electrically heated cigarette was mainly in the order of 109/cm3, and the particle volume concentration was in the order of 105 μm3/cm3. The particle size distribution profiles of aerosol were unimodal or bimodal, and the count median diameter was mainly in the range of 30~60 nm. There were obvious differences in physical properties of total and puff-by-puff release of the aerosol from different brands of electrically heated cigarettes. The particle number concentration, count median diameter and volume concentration of the aerosol puff-by-puff released from the electrically heated cigarettes showed a certain degree of instability.
