Determination of Methanol in Atmospheric Waste Gas by Packed Column Gas Chromatography
Determination of Methanol in Atmospheric Waste Gas by Packed Column Gas Chromatography Details:

Name: Packed Column

Chromatographic fixative: 5% polyethylene glycol
Carrier: graphite carbon black 80-120 mesh

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

Model: 5%Carbowax 20M Carbopack B

Application: HJ T33-1999 Determination of methanol in exhaust gas from stationary pollution sources by gas chromatography



At present, the main methods for the determination of methanol in the air are the magenta sulfurous acid colorimetric method and the gas chromatography method. The sensitivity of the colorimetric method is 25μg/5ml, which cannot meet the needs of methanol determination in the environment.

Gas chromatography uses pure water to absorb methanol in the air. From the spectrum of this method, it can be seen that the separation from ethanol is not ideal. When a large amount of ethanol and methanol coexist in the air, the separation of methanol will be adversely affected. .Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used a 5% Carbowax 20M Carbopack B packed column to measure methanol in exhaust gas with high efficiency and satisfactory results.
