Gas Chromatographic Determination of Methanol in Air and Waste Gas on Packed Column
Gas Chromatography Determination of Methanol in Air and Waste Gas on Packed Column 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%. Analyzed by gas chromatograph with FID, 5% Carbowax 20M Carbopack B packed column, methanol and ethanol can be separated (R=1.21), quantified by peak area method, the minimum detectable concentration of methanol is 0.2mg/m~3.
