Quantachrome Instruments High Pressure Gas Sorption Analyzer iSorb™ HP2

High pressure gas sorption measurements are important in the fields of carbon dioxide and methane sequestration, hydrogen storage, and gas separation. The iSorb-HP instruments (volumetric sorption apparatus) generate automatic measurements of full adsorption and desorption isotherms over a wide range of pressures and temperatures.The iSorb series is a family of four such analyzers; one and two-sample models each available with an upper pressure limit of 100bar or 200bar, complete with built in vacuum pumps and sample degassing capability. All models feature pressure transducers both in the dosing manifold and on the sample cell for maximum sensitivity; this also provides the iSorb-HP2 model the capability to simultaneously analyze two samples. Measurements are defined in terms of pressure or dose amount for both adsorption and desorption, equilibrium criteria, sample temperature (according to the heating /cooling device selected) and choice of equation of state (EoS)*:
