　　Haohan chromatography uses HH-PLOT U capillary column, internal standard, and hydrogen flame ion detector to detect the content of impurities ethanol, methyl formate, n-propanol, and isopropanol in industrial methanol. The experimental results show that the relative error of each impurity component in the standard solution determined by this method is 3.11% to 4.51%, and the relative standard deviation is 0.93% to 1.96%. It has good accuracy and precision and can be used for quality control analysis of impurities in industrial methanol
