传统卷烟和电子烟烟气气溶胶粒径分布研究

摘要

为了解传统卷烟和电子烟烟气气溶胶粒径分布特性，按照ISO的抽吸模式，分别对10个品牌的传统卷烟和电子烟进行测试。通过在线稀释，采用模拟循环吸烟机和快速粒径谱仪对气溶胶粒径和浓度进行了测试。结果表明：（1）在相同的抽吸条件下，传统卷烟气溶胶的颗粒、单位体积数浓度都比电子烟大；（2）在不同抽吸口数下，传统卷烟气溶胶粒径每口之间差异很大，而电子烟气溶胶粒径每口之间分布比较均匀。%Ten brands of traditional and electronic cigarettes were tested under ISO smoking regime to study particle size distribution in smoke aerosol of both traditional and electronic cigarette. Particle size distribution and number concentration were determined by on line dilution followed by using a smoking cycle simulator and a fast particulate spectrometer. Results showed that: (1) aerosol particles and number concentration of traditional cigarette surpassed those of electronic cigarette under same smoking regime; (2) aerosol particle size distribution of traditional cigarette was significantly different by puff, while aerosol particle size distribution of electronic cigarette remain unchanged by puff.
