摘　　要：利用单光子电离飞行时间质谱仪对吸烟模拟装置中的新鲜主流烟气进行实时在线检测,共测得40多种挥发性有机化合物,获得不同物质在逐口吸烟过程中含量的变化情况以及不同通风率的香烟烟气中的化合物含量情况。与此同时,使用主成分分析法对不同通风率的香烟种类的新鲜烟气的谱图进行分析,结果表明,在PCA散点图中,PC1=94%,PC2=3%,PC2=1%,三者之和达到98%,不同通风率的香烟的差异显著。实现了对逐口吸烟产生的新鲜主流烟中的有机成分进行在线检测分析。The single photon ionization time-of-flight mass spectrometer was used to detect the fresh mainstream smoke in the smoking simulation device.A total of more than 40 volatile organic compounds were detected.At the same time,the changes of different substances during the smoking process by mouth and the content of the compounds in the cigarette smoke with different ventilation rates were obtained.In addition,Principal Component Analysis was used to analyze the spectrum of fresh smoke of different types of cigarettes.The results showed that PC1=94%,PC2=3%,PC2=1%.It indicated that the differences in cigarettes with different ventilation rates were significant.In this study,on-line mass spectrometry was used to detect and analyze organic components in fresh mainstream cigarettes in puff by puff.
