为检测电子烟烟液中的挥发性成分，建立了顶空-固相微萃取（HS-SPME）-气相色谱质谱联用(GC/MS)方法，并采用该方法测定了5种不同的电子烟烟液。结果表明：①采用65μm聚二甲基硅氧烷/二乙烯基苯涂层纤维（PDMS/DVB），80℃萃取30 min，250℃下解吸5 min的样品前处理效果最佳。②1#~5#电子烟烟液分别分离鉴别出53，31，30，17和29种化合物，其中含量较高的是烯烃、醇类、酯类、烃类化合物。③1#样品5次重复试验，组分峰面积RSD的平均值为6.73%。④5种电子烟烟液中最重要的调香物质为柠檬烯，其次为β-蒎烯、月桂烯、薄荷醇和1-石竹烯；不同风格的电子烟烟液添加了彰显其口味的特征香味物质。该方法灵敏度高、重复性好，适用于不同电子烟烟液中挥发性成分的分析。

A method combining headspace solid-phase microextraction (HS-SPME) with gas chromatography-mass spectrometry (GC/MS) was developed for analyzing the volatile components in e-liquids. Five different e-liquids were tested with the developed method. The results indicated that: 1) The optimum pretreatment conditions were 65 μm polydimethylsiloxane/divinylbenzene (PDMS/DVB) coating assembly fiber, extracting for 30 minutes at 80 ℃, and desorbing for 5 minutes at 250 ℃. 2) 53, 31, 30, 17 and 29 compounds were identified in the 5 samples, respectively; among them, the main compounds were alkenes, alcohols, esters and hydrocarbons. 3) The average relative standard deviation of components’peak areas was 6.73%for 5 repeated tests of sample No.1. 4) The most important flavoring substance in the 5 e-liquids was limonene, followed by β-pinene, myrcene, menthol and 1-caryophyllene. Characteristic aroma substances were added into the e-liquids to enhance their flavor styles. This method features high sensitivity and good repeatability, it is suitable for the analysis of volatile components in e-liquids.
