PEG-20M 制浆废气中的甲醇测定毛细管柱的详细资料

制浆废气中的甲醇测定毛细管柱
制浆废气中的甲醇测定毛细管柱  详细信息：

名称：毛细管柱
规格：30m*0.25mm*0.25um
型号：PEG-20M


甲醇是制浆过程产生的主要的醇类污染物。浩瀚色谱（山东）应用技术开发有限公司先建立了一种利用顶空气相色谱法测定天然斜发沸石对废气中甲醇吸附量的方法。在该方法中,样品质量小于等于0.200 g时甲醇峰面积与样品质量呈线性关系,0.200 g吸附后的沸石在顶空进样器中80℃下平衡30 min可使吸附的甲醇的解吸达到平衡;该方法具有良好的精密度(RSD ≤ 3.09%)和准确度(回收率 92%),并可以应用到分子筛、木屑和蔗髓吸附甲醇量的测定中。

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.
