Volumetric Sorption Apparatus for Surface Area and Porosity Analysis – iSorb Series

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.

Key Features

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).
