Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a method of directly absorbing methanol from ambient air or industrial waste gas with pure water, using headspace sampling and gas chromatography for qualitative and quantitative determination. The minimum detectable mass concentration of this method is 0.500mg · m ^ -3, with a relative standard deviation of 4% -6.2% and a recovery rate of 88% -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 analysis; After actual sample measurement, it fully meets the monitoring requirements for methanol in ambient air and exhaust gas.
