Gas adsorption Isotherm System LEGADIS

The LEGADIS determines the adsorption isotherm for a combination of adsorbate (e.g. methane, CO2,) and adsorbent (coal, shale etc.). In other words, the system evaluates at equilibrium, the maximum volume of gas adsorbed onto an adsorbent, at a specific temperature and pressure. The latter is achieved by means of the isothermal volumetric method in which the pressures and volumes of a reference and test cell held at constant temperature, are continuously monitored. The apparatus is fully automated, allowing computer-controlled gas injection, pressure monitoring and data acquisition. Up to four testing chambers can be integrated into the system to allow simultaneous and independent testing.
