【摘要】 为准确评估加热卷烟逐口烟气释放量的稳定性，基于烟支损失质量（Tobacco lose mass,TLM）建立了加热卷烟烟气气溶胶质量浓度检测方法，利用搭建的加热卷烟抽吸和称量系统对4种加热卷烟（HTP-1～HTP-4）抽吸过程中的TLM和烟气气溶胶捕集量（Aerosol collected mass,ACM）进行测试，并基于TLM计算烟气气溶胶质量浓度。结果表明：(1)外界环境对TLM和ACM的影响较小，该检测方法能够准确测量逐口ACM和TLM；(2)4种加热卷烟的总TLM明显高于总ACM，且TLM的相对标准偏差（RSD）均小于ACM的RSD，表明以TLM表征气溶胶质量浓度更为准确；(3)基于TLM计算烟气质量浓度，综合考虑有效抽吸口数、逐口烟气质量浓度平均值及SD值，HTP-1的烟气逐口释放性能最优。该方法可为评估加热卷烟逐口烟气释放性能提供支持。更多还原

【Abstract】 To accurately assess the consistency of puff-by-puff delivery from heated tobacco products(HTPs),a method for measuring the aerosol mass concentration of HTPs based on tobacco lose mass(TLM)was developed. The TLM and the aerosol collected mass(ACM)of four kinds of HTPs were measured with an in-house HTP smoking and weighing system,and the aerosol mass concentration was calculated based on TLM. The results showed that:1)The ambient conditions had little influence on TLM and ACM,and the developed method could accurately measure the puff-by-puff ACM and TLM.2)The total TLM was significantly higher than the total ACM for the same HTP and the RSDs of the TLM was lower than that of the ACM,which indicated that it would be more accurate to characterize aerosol mass concentration on the basis of TLM. 3)Taking the TLM-based aerosol mass concentration,the effective puff number,the mean of puff-by-puff aerosol mass concentration and SD value into account,HTP-1 showed the best puff-by-puff delivery performance. This method provides a support for evaluating the puff-by-puff delivery performance of HTPs.更多还原
