分子筛吸附热的反相气相色谱 详细信息：

固定相：分子筛填充柱MS-5 Å

粒度：60-80目

规格：2m*3mm，4m*3mm，英制1/8，1/4

根据客户要求定制

应用：气体O2/N2/CH4/CO分离，效果良好

滕州市浩瀚色谱仪器技术服务有限公司，结合气相色谱分析方法的特征,应用反相气相色谱法,以N2、CO为探针分子,在不同温度下测定了新制备的分子筛-1、-2、-3、-4的保留时间,以保留时间的对数对温度倒数进行回归分析。结果得到线性关系良好的曲线,由此曲线计算得到这些分子筛对CO和N2的吸附热范围分别为26.60~30.12kJ,25.0~28.01kJ。本研究的结果表明,反相气相色谱法能测定出结构微小改变时的吸附热差别。

Reversed-phase gas chromatography for adsorption of molecular sieves
Reversed-phase gas chromatography of molecular sieve adsorption heat Details:

Stationary phase: molecular sieve

Particle size: 60-80 mesh

Specifications: 2m*3mm, 4m*3mm, inch 1/8, 1/4

Customized according to customer requirements

Application: Permanent gas O2/N2/CH4/CO separation, good effect

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd., combined with the characteristics of gas chromatography analysis method, using reversed phase gas chromatography with N2, CO as probe molecules, the newly prepared molecular sieves -1, were measured at different temperatures. 2, -3, -4 retention time, regression analysis of the reciprocal of the temperature with the logarithm of the retention time. As a result, a curve with a good linear relationship was obtained. From this curve, the adsorption heat ranges of CO and N2 of these molecular sieves were 26.60~30.12kJ and 25.0~28.01kJ, respectively. The results of this study indicate that reversed-phase gas chromatography can measure the difference in adsorption heat when the structure is slightly changed.
