Lab High Pressure and Constant Pressure Sorption Analyzer 


with Optional Function of  Gas Collection 


Constant Pressure Sorption Analyzer




Product description

Replace the high-pressure adsorption of the magnetic levitation balance gravimetric method, and realize the constant-pressure adsorption kinetic analysis of the volumetric method. (Patent No.: ZL2019 2 1740137.5)

Simulate the constant-pressure gas storage process, and provide not only adsorption capacity data, but also kinetic adsorption rate data support for constant-pressure hydrogenation and constant-pressure gas storage research.

Pressure range 0-20MPa, temperature range -196℃~1100℃ optional.

Optional TPD temperature-programmed desorption module, hydrogen absorption and desorption kinetics test, TPD temperature-programmed desorption rate and platform temperature. It is optional to increase the function of draining and collecting gas.

 

Test principle

After the sample is placed in the sample tube, it will first be filled with an inert gas for calibration (such as helium) to calibrate the volume occupied by the sample and the remaining free space volume (dead volume) of the sample tube, and then a certain amount of adsorbate The gas is filled into the sample tube (injecting gas), and the software will automatically record the adsorption amount under the pressure value at this time when the adsorption is balanced. This operation is then automatically repeated until the desired maximum pressure value is reached. We plotted the pressure value corresponding to the adsorption amount to obtain the adsorption isotherm.

For some samples, the adsorption capacity at different temperatures is completely different. At this time, we can test the change of the gas adsorption capacity of the sample at different temperatures according to the actual needs of users.

For all these complex operations, Best BSD-PH series high temperature and high pressure gas adsorption instrument has been fully automatic, and it can automatically process complex data models to evaluate the high temperature and high pressure adsorption performance of samples.
