| 摘 要： | 为准确分析卷烟主流烟气气相物中CO的逐口释放特征,改造了单孔道吸烟机,建立了一套基于可调谐二极管半导体激光吸收光谱(TDLAS)技术的卷烟主流烟气逐口在线分析系统。利用该系统,分析了管路和滤片夹持器残留对烟气逐口分析结果的影响,对4种不同类型卷烟中CO的逐口释放量进行了检测,探讨了其传递规律。结果表明:①清除残留前后CO的逐口传递规律明显不同;②在清除模式下,主流烟气中CO的释放量先降低后逐口增加,其中第2口的CO释放量最低。与传统检测方法相比,基于TDLAS技术的改造型单孔道吸烟机,能快速完成烟气中CO的检测,并有效避免烟气中其他成分的干扰。

| Abstract: | In order to accurately analyze the puff-by-puff release characteristics of CO in gas phase of mainstream cigarette smoke,an on-line puff-by-puff analysis system for cigarette smoke was established,which incorporated tunable diode laser absorption spectroscopy(TDLAS) technology with a modified single port smoking machine.The effects of cigarette smoke remained in pipeline and filter pad holder on the results of puff-by-puff analysis were analyzed with the system.The puff-by-puff release and transfer tendency of CO in mainstream smoke of cigarettes of four different types were analyzed.The results showed that:1) The puff-by-puff transfer tendency of CO obviously differed before and after flushing the residual smoke from pipeline and filter pad holder.2) Under the flushing mode,the puff-by-puff release of CO in mainstream smoke decreased at the first and second puffs then increased gradually with the minimum at the second puff.Comparing with traditional analysis methods,the modified single port smoking machine combined with TDLAS technology can complete the analysis of CO in cigarette smoke quickly and avoid the interference from other components in mainstream cigarette smoke effectively. |
