Packed column for detecting the short-time concentration of methanol in the air
Packed column for detecting the concentration of methanol in the air for a short time. 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 T33-1999 Determination of Methanol in Exhaust from Stationary Pollution Sources Gas Chromatography

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established an analysis method for pure water to absorb methanol in the air at low temperature, and to pre-treat the sample and concentrate the methanol. The use of gas chromatography hydrogen flame ionization detection improves the sensitivity of the method and reduces the detection limit of the method. When the sampling volume is 3L, the lowest detection concentration is 0.08mg/m3, the relative standard deviation of the analysis is 0.63%-4.60%, and the recovery rate is 99.3%-105.0%. It can meet the requirements of safe production, environmental protection and occupational health monitoring.
