Gas sorption analyzer
Using the Sieverts volumetric method, the sorption analyzer makes it possible to determine the amount of gas absorbed by a sample under controlled pressure and temperature conditions. It can be used to analyze H2, CO2, CH4, N2, and Ar sorption. The unit allows for interfacing with the IMI system in conjunction with an automatic manometric sorption analyzer, enabling PCT (pressure-composition-temperature) isotherm measurements. It also makes it possible to study the kinetics of the sorption-desorption process and the persistence of materials with cyclic gas absorption and desorption over a given temperature and pressure range. The system contains a reaction chamber with a 10 cm3 capable of attaching a buffer volume, enabling measurements with sufficient accuracy for small samples.
