摘要
建立了一种用毛细管气相色谱法（Capillary Gas Chromatography,简称FID）测定白酒中甲醇和杂醇油的方法,对程序升温中的温度和时间、载气流速等色谱条件进行了优化。结果表明,甲醇及杂油醇浓度在0.04-1.00 g/L内呈良好的线性关系（≥0.9991）,样品加标回收率在89.24%-93.21%,该方法准确、可靠、快速。
The capillary gas chromatography method with the optimized temperature and time in raising temperature procedure and velocity of carrier flow was established for determinating methanol and fusel oils in alcohol.The results show that the determination method provides a good linear response（≥0.9991） when the concentration of methanol and fusel oils is 0.04～1.00 g/L and the recovery rate is 89.24%～93.21%,which expresses the method is of presision,reliability and rapid.
