　　HJ/T33-1999 Determination of Methanol in Fixed Pollution Source Exhaust Gas Gas Chromatography Method "elaborates on the principles of the method, selection and optimization of chromatographic conditions, curve preparation, and other aspects. It also describes the selection and optimization of chromatographic conditions, curve preparation, conclusions, and shortcomings in the process of establishing the method, and shares and exchanges them with everyone.

　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used a graphitized carbon black packed column to determine the total recovery rate of methanol gas samples, which was 95.7%, with a coefficient of variation of%. The recovery rate of low content methanol samples was greater than 90%, with a coefficient of variation of about 5%. Using a gas chromatograph with FID for analysis, methanol and ethanol can be separated (R=1.21), quantified by peak area method, and the lowest detectable concentration of methanol is 0.2mg/m3.
