制漿廢氣中的甲醇測定毛細管柱
制漿廢氣中的甲醇測定毛細管柱  詳細信息：

名稱：毛細管柱
規格：30m*0.25mm*0.25um
型號：PEG-20M


甲醇是制漿過程產生的主要的醇類污染物。浩瀚色譜（山東）應用技術開發有限公司先建立了一種利用頂空氣相色譜法測定天然斜發沸石對廢氣中甲醇吸附量的方法。在該方法中,樣品質量小于等于0.200 g時甲醇峰面積與樣品質量呈線性關系,0.200 g吸附后的沸石在頂空進樣器中80℃下平衡30 min可使吸附的甲醇的解吸達到平衡;該方法具有良好的精密度(RSD ≤ 3.09%)和準確度(回收率 92%),并可以應用到分子篩、木屑和蔗髓吸附甲醇量的測定中。

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.
