Dynamic Sorption Breakthrough Analyzer

The dynaSorb BT series provides unique capabilities to investigate arbitrarily complex dynamic sorption processes in a uniquely safe and easy-to-use bench-top instrument. Technical adsorbents can be investigated under authentic process conditions in a broad temperature and pressure range with adjustable gas flow rates and well-defined gas compositions.
