摘　　要：使用预浓缩-气相色谱质谱法对6种不同口味电子烟抽吸过程中释放的特征挥发性有机物进行了定量分析和组分筛查。乙醇是所有化合物中检出率最高,浓度最高的化合物,浓度范围为2197~6211mg/m3,定量目标化合物中还有乙酸乙酯、丙烯醛和异丙醇检出,组分筛查出特殊风味的电子烟烟气中还存在大量的酯类、烯烃类等化合物。在测定的6种不同口味电子烟烟气中醇类物质占比最大,均在90%以上,酯类、烯烃类等其他种类物质占比在0.1~7.8%之间。模拟电子烟的抽吸过程中,特殊风味电子烟VOCs吸入量大于烟草味电子烟。Characteristic volatile organic compounds(VOCs)in six different flavors of sucking emissions from E-cigarettes were determined and screened using pre-concentrating gas chromatography-mass spectrometry(GC/MS).Among all the compounds,ethanol exhibited the highest detection rate and concentration,ranging from 2197 to 6211mg/m3.Ethyl acetate,acrolein,and isopropanol were also detected among the quantifiable target compounds.Component screening revealed the presence of numerous esters,olefins,and other compounds in the electronic cigarette smoke,contributing to its unique flavors.Of the six different flavors analyzed,alcohols constituted the highest proportion,exceeding 90%,while esters and olefins accounted for 0.1%to 7.8%of the composition.During the simulated vaping process,the intake of VOCs from E-cigarettes with special flavors exceeded that of tobacco-flavored ones.
