Determination of Methanol in Ambient Air and Waste Gas from Stationary Pollution Sources by Headspace-Gas Chromatography
Headspace-Gas Chromatography Determination of Methanol in Ambient Air and Stationary Pollution Source Waste Gas 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



Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a combined analytical method for the determination of methanol in gas by headspace-gas chromatography. Methanol in gas samples is vaporized in a headspace instrument to achieve gas-liquid equilibrium, and in the optimized analysis Gas chromatography was used to determine the methanol in the sample under the conditions of 1. The results: the average recovery rate of methanol in the ambient air was 91.0%~108%, and the average recovery rate of methanol in the pollution source exhaust gas was 82.0%~97.5%. The correlation coefficient of the standard curve of methanol is r>0.9999, and the correlation coefficient of the standard curve of methanol in the waste gas of pollution source is r>0.9999. This method adopts headspace gas chromatography, and the amount of solvent is small, which is suitable for the determination of methanol in ambient air and stationary pollution source waste gas. measure.
