Determination of Methanol in Ambient Air and Waste Gas by Pure Water Absorption Headspace-Gas Chromatography
Determination of Methanol in Ambient Air and Waste Gas by Pure Water Absorption Headspace-Gas Chromatography Details:

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established the use of pure water to directly absorb methanol in ambient air or industrial waste gas, headspace sampling, and gas chromatography for qualitative and quantitative determination. The minimum detected mass concentration of this method was 0.500 mg·m^-3, the relative standard deviation was between 4% and 6.2%, and the recovery rate of standard addition was between 88% and 111%. The results show that the method is simple and sensitive, with good linear range, low detection limit, good precision, and accurate qualitative and quantitative determination. It can fully meet the monitoring requirements of methanol in ambient air and waste gas by actual sample determination.
