在电子烟烟碱液未经预处理以及经历在空气中多次蒸馏预处理两种条件下，采用热裂解气相色谱质谱(Py-GCMS)检测了电子烟烟碱液组分变化情况。未经预处理进行Py-GCMS时，由于烟碱液气化时与空气隔绝，气体组分的物质类型稳定，包含丙二醇、丙三醇和尼古丁，尼古丁含量低于10%；经历高温下空气中反复蒸馏预处理的烟碱液，气化后组分的物质类型和比例都与预处理的温度有关，蒸馏温度160℃时，尼古丁含量达到了21.07%。

Pyrolysis-Gas chromatography mass spectrometry method is used to analyze the relation between temperature and component and content of nicotine solution of electronic cigarette at two situations, namely without pretreatment on nicotine solution and after nicotine solution being evaporated five times in the air at set temperature. For the former situation, nicotine solution shows stable components, Propylene Glycol, Glycerin and nicotine, in which the content of nicotine is always lower than 10%. This is because nicotine solution is isolated from air when evaporating. For the latter situation, the component and content all change with evaporating temperature. When evaporating temperature is 160 ℃, the content of nicotine comes to 21.07%.
