Application: HJ T33-1999 Determination of Methanol in Exhaust Gas from Stationary Pollution Sources Gas Chromatography

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses pure water to directly absorb, and the total recovery rate of enrichment of high-content methanol gas samples with A, B, and secondary absorption liquids is 95.7%, and the coefficient of variation%: the recovery rate of low-content methanol samples It is greater than 90%, and the coefficient of variation is about 5%. Analyze with a gas chromatograph with FID, 5% Carbowax 20M Carbopack B is the stationary phase, methanol and ethanol can be separated (R=1.21), quantified by the peak area method, the minimum detectable concentration of methanol is 0.2mg/m~3 .
