Packed column to measure methanol in ambient air and exhaust gas
Packed column measures methanol in ambient air and exhaust gas. Details:

Name: Packed column
Chromatographic stationary liquid: 5% polyethylene glycol
Carrier: Graphite carbon black 80-120 mesh

Specification: 2m*3mm, 2m*1/8

Model: 5% Carbowax 20M Carbopack B
Application: HJ/T 34-1999 Determination of Vinyl Chloride in Exhaust from Stationary Pollution Source Gas Chromatography

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. 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 is 0.500mg· m-3, the relative standard deviation is between 4% and 6.2%, and the recovery rate of standard addition is between 88% and 111%. The results show that the method is simple and sensitive, with good linear range, low detection limit, good precision, and qualitative Quantitative and accurate; measured by actual samples, it fully meets the monitoring requirements for methanol in ambient air and exhaust gas.
