XEMIS-100 Gravimetric Sorption Analyzer

Description

The XEMIS-100 gravimetric sorption analyzer is a versatile instrument from Hiden Isochema for advanced materials characterization related to energy and polymer science. It functions by recording precise mass uptake or loss of a sample when exposed to controlled gas environments at specific temperatures and pressures. This capability is applied to key research areas such as energy gas storage (e.g., hydrogen, methane), high-pressure thermogravimetric analysis (TGA), and the characterization of polymer membranes for gas separation. The analyzer can test samples weighing between 1 mg and 5 g. It is capable of operating across a wide thermal range from 77 K to 500 °C and can sustain pressures up to 170 bar, with an optional 200 bar configuration. A defining feature is its active pressure control, which provides stable regulation across a vast pressure range. The system's symmetric geometry is engineered to reduce buoyancy effects, a critical factor for accuracy in high-pressure gravimetric measurements. The instrument is designed to be compatible with diverse and challenging gas species, including flammables and corrosives. Fully automated, the XEMIS-100 integrates measurements for sorption isotherms, isobars, and high-pressure TGA into a single platform, utilizing the IGA method for efficient analysis of sorption equilibria and kinetics.
