Determination of Methanol in Gas Samples by Headspace-Packed Column Gas Chromatography
Determination of methanol in gas samples by headspace-packed column gas chromatography. Details:
Name: Packed column
Chromatographic statio
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 Statio
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 item The air equilibrium temperature is 80 ℃, and the equilibrium time is 20 min. It is separated with a 5% Carbowax 20M Carbopack B packed column. When detected by a hydrogen flame io
