提出了同时测定新型卷烟气溶胶中水、烟碱、1，2-丙二醇和丙三醇的气相色谱双柱双检测器法。采用Φ 44 mm剑桥滤片捕集5支新型卷烟中气溶胶总粒相物，剑桥滤片用20 mL含3种内标的异丙醇溶液（乙醇为水的内标，2-甲基喹啉为烟碱的内标，1，4-丁二醇为1，2-丙二醇和丙三醇的内标）振荡萃取10 min，萃取液过0.22 μm滤膜后进行气相色谱分析。采用Porapak Q²填充柱和热导检测器检测水，采用DB-ALC色谱柱和氢火焰离子化检测器检测烟碱、1，2-丙二醇和丙三醇，内标法定量。结果表明：水、烟碱、1，2-丙二醇和丙三醇的质量浓度在一定范围内与其峰面积和内标峰面积的比值呈线性关系，检出限（3S/N）分别为0.08，0.01，0.02，0.05 mg·支^-1。按标准加入法进行回收试验，回收率为92.3%~103%，测定值的相对标准偏差（n=6）为2.4%~9.8%。

A gas chromatography method was applied to the simultaneous determination of water, nicotine, 1,2-propylene glycol and glycerol in the aerosol of heat-not-burn cigarettes with dual columns and dual detectors. The total particulate matters (TPMs) in the aerosol of 5 heat-not-burn cigarettes were captured by Φ 44 mm Cambridge filter pad, then the pad was extracted with 20 mL of isopropanol solution containing three internal standards (Ethanol was the internal standard of water, 2-methyl quinaldine was the internal standard of nicotine, and 1,4-butanediol was the internal standard of 1,2-propanediol and glycerol) for 10 min, the extraction solution was filtered with 0.22 μm filter membrane and analyzed by gas chromatography (GC). The water was separated by a Porapak Q² packed column and detected by a thermal conductivity detector (TCD), while nicotine, 1,2-propylene glycol and glycerol were separated by a DB-ALC column and detected by a hydrogen flame ionization detector (FID). Internal standard method was adopted in quantitative analysis. As shown by the results, linear relationships between the ratio of peak areas of water, nicotine, 1,2-propylene glycol and glycerol to that of their internal standards and their mass concentration were found in definite ranges, with detection limits (3S/N) of 0.08, 0.01, 0.02, 0.05 mg·cig^-1, respectively. Test for recovery was made by standard addition method, giving results in the range of 92.3%-103%, and RSDs (n=6) ranged from 2.4% to 9.8%.
