Determination of Methanol in Air by Gas Chromatography with Packed Column
Determination of Methanol in the Air by Gas Chromatography with Packed 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) Application Technology Development Co., Ltd. is discussing the detection method of silica gel tube adsorption-packed column gas chromatography for the determination of methanol in the workplace air. The methanol in the workplace is collected with a silica gel tube, and after hydrolysis and adsorption, it is subjected to 5% Carbowax 20M Carbopack B Chromatographic column separation, hydrogen flame ionization detector (FID) detection, qualitative retention time, peak area quantification. The results show that methanol and ethanol can be completely separated, the linear correlation coefficient is greater than 0.999, the precision RSD range is 1.84-4.60%, plus The standard recovery rate is 90-110%, and confirmed by gas chromatography mass spectrometry. Conclusion This method can effectively separate methanol and ethanol, accurately determine methanol in the air, and is suitable for the determination of methanol in the air on site.
