在这项研究中，使用基于激光的单光子电离飞行时间质谱仪来表征香烟侧流烟雾（SSS）发射的化学成分。SSS是由不同类型的香烟（2R4F研究卷烟；Burley， Oriental和Virginia单烟草型香烟）在单端口吸烟机上吸烟产生的，并使用所谓的鱼尾烟囱装置收集。使用此设置，执行了几个SSS组件的气泡解析量化。对SSS排放动力学的研究表明，各种物质的浓度分布可以分为几组，要么取决于冒烟的发生，要么不受冒烟过程中燃烧区变化的影响。吸一口烟后直接产生的SSS排放物与主流烟雾（MSS）的成分非常相似。在闷烧阶段，观察到MSS和SSS之间的明显差异。SSS和MSS的化学特征的变化也可能对环境烟草烟雾有重要影响，这在很大程度上是由SSS决定的。此外，SSS的化学成分受烟草类型的强烈影响。因此，白肋烟含氮量较高导致SSS中含氮物质的检测量增加。
In this study, the chemical composition of sidestream smoke (SSS) emissions of cigarettes are characterised using a laser-based single-photon ionisation time-of-flight mass spectrometer. SSS is generated from various cigarette types (2R4F research cigarette; Burley, Oriental and Virginia single-tobacco-type cigarettes) smoked on a single-port smoking machine and collected using a so-called fishtail chimney device. Using this setup, a puff-resolved quantification of several SSS components was performed. Investigations of the dynamics of SSS emissions show that concentration profiles of various substances can be categorised into several groups, either depending on the occurrence of a puff or uninfluenced by the changes in the burning zone during puffing. The SSS emissions occurring directly after a puff strongly resemble the composition of mainstream smoke (MSS). In the smouldering phase, clear differences between MSS and SSS are observed. The changed chemical profiles of SSS and MSS might be also of importance on environmental tobacco smoke which is largely determined by SSS. Additionally, the chemical composition of the SSS is strongly affected by the tobacco type. Hence, the higher nitrogen content of Burley tobacco leads to the detection of increased amounts of nitrogen-containing substances in SSS.
