Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses pure water for direct absorption, and the total recovery rate of high-content methanol gas samples enriched with A, B, and secondary absorption liquids is 95.7%, and the coefficient of variation %: The recovery rate of low-content methanol samples More than 90%, the coefficient of variation is about 5%. The 5% Carbowax 20M Carbopack B packed column was used for analysis with a gas chromatograph with FID. Methanol and ethanol could be separated (R=1.5), and quantified by peak area method. The minimum detectable concentration of methanol was 0.2 mg/m~3.
