The current methods for determining methanol in the air mainly include fuchsin sulfurous acid colorimetry and gas chromatography. The sensitivity of the colorimetric method is 25μg/5ml, which cannot meet the needs of methanol determination in the environment. Gas chromatography uses pure water to absorb methanol in the air. From the spectrum of this method, it can be seen that the separation with ethanol is not ideal.When a large amount of ethanol and methanol coexist in the air, the separation of methanol will have an adverse effect.


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses 5% Carbowax 20M Carbopack B packed column, and the area external standard method is used for quantification, with satisfactory results.
