Determination of Methanol in Exhaust Gas by Headspace Gas Chromatography
Determination of methanol in exhaust gas by headspace gas chromatography. 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. established a pure water absorption-headspace gas chromatography method for the determination of methanol in exhaust gas. The methanol in the exhaust gas was absorbed by pure water, and the absorption liquid was used for headspace sampling to optimize the sample storage and headspace sampling conditions. The detection limit is 25μg/m~3, and the recovery rate of standard addition is 91.4%-107%. The method is fast, simple, and highly accurate, which is in line with the development trend of modern instruments.
