mixSorb L (formerly dynaSorb BT) – breakthrough curve analysis

The mixSorb L series provides unique capabilities to investigate arbitrarily complex dynamic sorption processes in a uniquely safe and easy-to-use bench-top instrument. Technical adsorbents such as zeolites, active carbons, silica gels, etc. can be investigated under authentic process conditions at a broad temperature (-20 °C to 400 °C) and pressure (up to 85 bar) range, with adjustable gas flow rates up to 40 L/min and well-defined gas compositions.

The mixSorb S series provides unique capabilities to investigate novel materials, like MOFs COFs etc. by mixed gas adsorption, especially for R&D.

An overview of the models of the mixSorb L series can be found below:
