IMI – FLOW versalite manometric gas sorption analyzer

The IMI-FLOW combines the manometric gas sorption capabilities of all IMI analyzers with flowing mode operation and integrated mass spectrometry. Manometric mode offers high accuracy isotherm determination to 200 bar, while the flowing mode provides complete control of pressure, composition and flow rate. Integrated mass spectrometry allows downstream gas analysis for TPD and advanced methods.

In the IMI-FLOW, thermal desorption is performed into an inert carrier gas stream and detected using a downstream MFC or an optional integrated quadrupole mass spectrometer. The design of the instrument incorporates a low volume gas pathway for both a rapid response and maximum sensitivity. The addition of a dynamic sampling quadrupole mass spectrometer for evolved gas analysis, combined with multiple flow streams, also allows the 

performance of gas mixture and exchange experiments. The versatile and integrated nature of the IMI-FLOW, which allows direct control of a close-coupled mass spectrometer from the IMIwin software suite, makes it a unique and sophisticated analysis system
