Determination of Methanol in Waste Gas by Gas Chromatography with Pure Water-Headspace Packed Column
Purified water-headspace packed column gas chromatography to measure methanol in exhaust 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

Pure water absorbs methanol in the gas and analyzes it by headspace packed column gas chromatography. Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. focused on testing and discussing the analytical conditions for the determination of methanol by headspace 5% Carbowax 20M Carbopack B packed column gas chromatography. The experimental results show that the determination of methanol by pure water-headspace packed column gas chromatography is simple, the standard curve has a good linear regression, and the method has high sensitivity, precision and accuracy, which is in line with the development trend of modern instruments.
