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.

Gas chromatographic measurement of methanol in ambient air and waste gas from stationary sources. Test spectrum:
