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.
