IMI-Flow

State-of-the-Art Dynamic Flow and Thermal Desorption System

The IMI-FLOW is a state-of-the-art dynamic flow and thermal desorption analyzer. It combines the static mode manometric sorption measurement capabilities of the full IMI range with unique dynamic (flowing) mode operation, which allows the performance of Temperature Programmed Desorption (TPD), as well as gas mixture and exchange experiments.

High performance MFCs are used to regulate the flow of gas, while the integrated sample reactor heating system allows the precise control of the applied linear thermal ramp rates for temperature-programmed studies. 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.
