The XEMIS can be used with a wide range of different sorptive species. Contact us now to discuss your specific requirements.

The XEMIS is a high accuracy sorption microbalance for precision weighing in extreme environments. Available as a standalone microbalance or as part of a fully integrated sorption analyzer, the XEMIS provides remarkable flexibility, as well as outstanding weighing stability and accuracy.


The XEMIS microbalance incorporates Hiden Isochema's unique exosensing technology, which allows gravimetric sorption analysis at high temperatures and high pressures, under a combination of conditions previously unachievable with commercial sorption microbalance instrumentation.
