2m*3mm methanol dedicated column 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) Applied Technology Development Co., Ltd. has carried out research on the method of automatic headspace sampler combined with gas chromatography for the determination of methanol in ambient air and exhaust gas. The results show that when the sample is added with 4 g of sodium chloride, the headspace equilibrium temperature is 80°C, and the equilibrium time is 20 min, it is separated with a 5% Carbowax 20M Carbopack B methanol column and detected by a hydrogen flame ionization detector, and the methanol standard is obtained. The curve equation is y=23 415x+237.2, the correlation coefficient (R) is 0.999 4; the detection limit is 0.002 mg/m3, the relative standard deviation (n=6) is 0.5%, and the recovery rate of standard addition is 98.9%. The method is simple, sensitive, good resolution, and low detection limit.
