摘　　要：为分析电子烟烟气粒相物挥发性成分,建立了一种顶空(HS)-气相色谱质谱联用(GC/MS)方法,测定了3种水果味电子烟烟气粒相物挥发性成分。研究表明,顶空平衡温度120℃,平衡时间20 min时的捕集效率最佳; 3种电子烟中分别鉴定出26、23、20种烟气粒相物挥发性成分,其中相对含量较高的是丙二醇,均占每种总含量的80%以上; 5次重复实验的组分峰面积的相对标准偏差(RSD)为3. 64%,方法重复性良好;电子烟烟气中主要的致香成分为2,3-丁二酮、乙酸乙酯、乙酸甲酯、反-3-己烯醇、3-甲基-2-戊醇、2-庚醇。实验方法操作简便、重复性好、无溶剂残留,适于电子烟烟气粒相物挥发性成分的分析。In order to analyze the volatile component of the E-cigarette smoke particulates,a headspace( HS)-gas chromatographymass spectrometry( GC/MS) method was established to determine the volatile component of three fruit-flavored E-cigarette smoke particulates.The results showed that the capture efficiency with the headspace equilibrium temperature of 120 ℃ and the equilibrium time of 20 min was the best. Three E-cigarette smoke particulates identified 26,23,20 volatile components,respectively,of which the higher content is propylene glycol accounting for more than 80% of its total content.RSD of the component peak area of the five repeated tests was 3. 64%,and the method was good repeatability. The main aroma components in electronic cigarette smoke were 2,3-butanedione,ethyl acetate,methyl acetate,trans-3-hexenol,3-methyl-2-pentanol,2-heptanol. The experimental method was simple in operation,good in repeatability and solvent-free,and was suitable for analysis of volatile components of E-cigarette smoke particulates.
