IMI-PSI

Extended Pressure Sorption Analysis System for Nanoporous Media

The IMI-PSI is an extended pressure manometric sorption analysis system for nanoporous media. It is specifically designed for the investigation of gas sorption by nanoporous materials, at both low (cryogenic) and elevated temperatures, up to gas pressures of 200 bar.

Supplied with an immersion reactor and a high performance Dewar, the IMI-PSI provides optimal thermal stability at cryogenic temperatures, which is crucial for high accuracy gas sorption measurement. The IMIwin software features a range of data fitting functions, including BET analysis for the determination of specific surface area, and DA and HK analysis for the characterization of pore size distributions.
