Capillary Column for Determination of Methanol in Pulping Waste Gas
Capillary column for determination of methanol in pulping waste gas Details:

Name: Capillary Column
Specification: 30m*0.25mm*0.25um
Model: PEG-20M


Methanol is the main alcohol pollutant produced in the pulping process. Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. first established a method using headspace gas chromatography to determine the amount of methanol adsorbed by natural clinoptilolite in exhaust gas. In this method, when the sample mass is less than or equal to 0.200 g, the methanol peak area has a linear relationship with the sample mass. 0.200 g of the adsorbed zeolite is equilibrated in the headspace sampler at 80°C for 30 minutes to achieve the equilibrium of the desorption of the adsorbed methanol. ; This method has good precision (RSD ≤ 3.09%) and accuracy (recovery rate of 92%), and can be applied to the determination of molecular sieve, wood chips and sugarcane pith adsorption of methanol.
