introduction

The XEMIS-003 is a dynamic gas sorption analyzer incorporating multiple controllable inlets with combined pressure and flow control, and the option of integrated mass spectrometry. Changes in sample mass are measured as a function of applied temperature and pressure to determine isotherms, isobars and sorption kinetics. Designed for operation with a full range of gas and vapor species including corrosives and flammables, the XEMIS series features a controllable pressure range covering 7 orders of magnitude.

The XEMIS series offers reproducible, high resolution, high accuracy measurements even with small sample sizes or small uptakes, and performance unrivalled in a high pressure sorption analyzer.
