XEMIS Gravimetric Microbalance
The Shiflett Lab is excited to announce that XEMIS Gravimetric Microbalance is now operational. The XEMIS Gravimetric Microbalance was installed in LEEP2 Laboratory 2444 by Hiden Isochema (United Kingdom) in early February. The XEMIS system is designed for studying a variety of applications including gas sorption analysis, kinetic analysis, hydrogen and methane storage, carbon dioxide sequestration, natural gas separation and purification. The system was designed by Hiden Isochema Engineers with Exosensing technology which allows operation with corrosive and flammable gases over a broad range in pressure (0 to 170 bar). The symmetric geometry of the system provides high precision and minimizes the buoyancy effects during the measurements. The various thermostat options (furnace, water bath, cryo cooling) allows measurements over a wide range in temperature from 77 K to 773 K. The system can handle both solid and liquid samples with a maximum weight of 5 g. The measurement capacity from 0 – 200 mg has an accuracy of 0.2 μg. A safety interlock system has been designed which allows for continuous unattended operation. The Shiflett Lab is the only academic lab in the United States and one of only six laboratories in the world which have a XEMIS gravimetric microbalance.
