In the areas of methane storage, carbon dioxide sequestration, gas separation and hydrogen storage, high pressure adsorption measurements are important. Quantachrome's iSorb-HP volumetric sorption apparatus instruments enable automatic measurements of full desorption and adsorption isotherms over a broad range of temperatures and pressures.
The main features of the iSorb Series are:
The iSorb series is a family of four high-pressure sorption analyzers with 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.
Pressure transducers are featured in all models both on the sample cell and the dosing manifold for maximum sensitivity hence this model can analyze simultaneously two samples.
Measurements are specified in terms of dose amount or pressure, sample temperature, equilibrium criteria and choice of equation of state (EoS).
Analysis temperatures are achieved either by recirculator bath (-20°C to 100°C, see below), cryocooler (77K-320K), or heating mantle (up to 400°C).
