Gas chromatographic measurement of methanol in ambient air and exhaust gas from stationary sources
Gas chromatographic measurement of methanol in ambient air and exhaust gas from stationary sources. 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 headspace-gas chromatography combined analysis method for the determination of methanol in the gas. The methanol in the gas sample is vaporized in a headspace instrument to achieve a gas-liquid balance, and the analysis is optimized Under the conditions, gas chromatography is used to determine the methanol in the sample. Results: The average recovery rate of methanol in the ambient air is 91.0%~108%, and the average recovery rate of methanol in the exhaust gas of the pollution source is 82.0%~97.5%. The determination of the ambient air The correlation coefficient of the standard curve of methanol is r>0.9999, and the correlation coefficient of the standard curve of the determination of methanol in the exhaust gas of pollution sources is r>0.9999. This method uses headspace gas chromatography with a small amount of solvent, which is suitable for the determination of methanol in the exhaust gas of ambient air and fixed pollution sources. Determination.
