mixSorb S series – breakthrough curve analyser

The mixSorb S series provides unique capabilities to investigate novel materials, like MOFs, COFs etc. by mixed gas adsorption. Novel materials are in the focus of research in recent last years. These materials can have very high selectivity’s due to their extraordinary surface chemistry and have to be investigated by mixed gas sorption for a deeper understanding of their sorption behaviour.


In contrast to the mixSorb L series, the mixSorb S series is designed for very small sample amounts (powders). Especially R&D groups have now the possibility to measure newly synthesized materials by complex dynamic sorption processes in a wide field of different gas- and gas/vapor-mixtures by using different parameters like pressure, temperature gas velocity/dwell times, cycle tests and much more. These experiments allow to get data, next to the effective adsorption performance, of kinetics, co-adsorption phenomenon or displacement effects, sorption selectivity’s, data of gas mixture adsorption and heat balance of the sorption process.

By using the available vapor option it is possible to work up to 2 completely independent evaporators to form fully automated individually gas/vapor mixtures fully automated. These data allow a profound look at the co-adsorption phenomenon or displacement effects.

The related modelling software 3P sim made it possible to calculate and to modify pure gas isotherms as well as breakthrough curves and to calculate the behaviour of gas/vapor-mixture equilibria.
