Determination of Methanol in Air and Waste Gas by Gas Chromatography
Gas Chromatographic Determination of Methanol in Air and Waste Gas Details:


Name: Packed column
Chromatographic stationary liquid: 5% polyethylene glycol
Carrier: Graphite carbon black 80-120 mesh

Specification: 2m*3mm, 2m*1/8

Model: 5% Carbowax 20M Carbopack B

Application: HJ T33-1999 Determination of Methanol in Exhaust 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, graphitized carbon black support, methanol and ethanol can be separated (R=1.21), quantified by the peak area method, the minimum detected concentration of methanol is 0.2mg/m~3.
