摘　　要：建立甲醇厂废水中甲醇、乙醇、杂醇的气相色谱分析方法。以INNOWAX毛细管为分离柱,使用氢火焰离子化检测器,以氮气为载气、尾吹气,分流比为3:1。用峰面积加和计算杂醇含量,用外标法定量。操作简单,灵敏度高,分离效果好,线性范围宽,具有较高的准确度和较好的重现性。This paper sets up gas chromatography for analysis of methanol, ethanol, and fusel in waste water from methanol plant. The method uses INNOWAX capillary tube as separator column, uses H2 flame ionic detector, and uses N2 as carrier gas and tail purging gas, the split ratio is 3 ： 1. Peak area addition is used to calculate fusel content, and external standard method is used to determine the quantity. This method is easy in operation, with high sensitivity, good separating effect, wide linear range, as well as high accuracy and good repeatability.
