Determination of Methanol in Ambient Air by Static Headspace-Gas Chromatography
Static Headspace-Gas Chromatography Method for Determination of Methanol in Ambient Air 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. used static headspace-gas chromatography to study the determination of methanol in ambient air. Through a series of condition experiments, the headspace equilibrium temperature, headspace equilibrium time, sodium chloride added amount and other factors were optimized. The detection limit of the method, linear range and recovery rate of standard addition were determined, and the actual samples were tested at the same time. The results show that the detection limit of this method is 0.05mg/m3, and the recovery rate of the actual sample test is 86%-106%, which is suitable for the determination of methanol in ambient air.
