This standard applies to the determination of methanol from fixed sources of organized emissions and unorganized emissions. Calculated by 3 times the noise chromatographic peak height value, when the chromatographic injection volume is 1.0ml, the detection limit of the method is 2mg/m3; the concentration range of quantitative determination is 5.0～104mg/m3. To


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 was used to determine the methanol in the sample. Results: The average recovery rate of methanol in the ambient air was 91.0%~108%, and the average recovery rate of methanol in the exhaust gas of the pollution source was determined to be 82.0%~97.5%. The determination of the methanol in 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 ambient air and fixed pollution source exhaust gas.
