摘要
建立了填充柱气相色谱法测定烟用香精中水、乙醇、丙二醇含量的方法。该法以丁酮为溶剂、异丙醇为内标 ,采用 2m× 3mmi.d .内填GDX - 10 2的不锈钢柱 ,TCD检测器。一次进样可以完成水、乙醇、丙二醇的含量分析 ,方法简便、快速、准确。
A method for determining the content of water, ethanol and propylene glycol in tobacco flavor by gas chromatography with a packed column was established. Tobacco flavor was extracted with butanone containing a little amount of iso\|propanol (internal standard) and then analyzed by GC. The column used was a 2m×3mm i.d. stainless steel tube packed with GDX-102 stationary phase and the detector was TCD. The content of water, ethanol and propylene glycol in tobacco flavor could be determined respectively by one injection. The method is simple, rapid and accurate.
