摘　　要：为了快速测定卷烟烟丝中1,2-丙二醇和丙三醇的含量,通过气相色谱-质谱联用仪(GC-MS)结合内标法建立了上述两种保润剂的定量分析方法。结果表明:1,2-丙二醇和丙三醇的相对标准偏差(RSD)均在5%以内,回收率分别在98.59%~103.87%和95.12%~104.76%范围内,检测限和定量限分别为3.28、10.95μg/g和15.95、53.18μg/g,表明该法具有较好的重现性和准确性。与行业标准方法相比较,两种方法之间没有显著性差异,表明该法可用于快速地测定卷烟烟丝中1,2-丙二醇和丙三醇的含量。In order to establish a method to determine the content of humectants in cigarette filler,gas chromatography-mass spectrometry and internal standard method for determining 1,2-propylene glycol and glycerol contents in cigarette filler was established.The results showed the relative standard deviation of 1,2-propylene glycol and glycerol were less than 5%,the recovery ranges of 1,2-propylene glycol and glycerol were 98.59%~103.87%and 95.12%~104.76%,respectively.Their detection limits and quantitative limits were respectively 3.28μg/g,10.95μg/g and 15.95μg/g,53.18μg/g,which showed the method had good reproducibility and accuracy.There was not significant difference between the method and industry standard method,which showed that the method can be used to quickly determine the humectant content in cigarette filler.
