A wide range of adsorption isotherms can be measured under various temperature conditions (e.g., N2 at 77.4 K, Ar at 87.3 K, CO2 at 273 K), which can be directly used for BET surface area determination and pore size distribution analysis using advanced GCMC / QSDFT models.

With conventional methods, evaluating the isosteric heat of adsorption at cryogenic temperatures required multiple adsorption isotherms within a narrow temperature range, which was technically challenging and time-consuming. BELCRYO X revolutionizes this process by enabling precise measurements at arbitrary temperatures for various gases—making accurate isosteric heat evaluation simpler, faster, and more flexible than ever before.
Example: N2 isosteric heat evaluation at 77.4 K using adsorption isotherms at 77.4 K, 82.4 K, and 87.4 K.
By combining BELCRYO X with instruments such as the BELSORP MAX X HP, a wide range of gas adsorption isotherms – including hydrogen and methane storage studies and CO2 separation – is obtainable across a broad temperature range and pressure conditions, from cryogenic to high temperature and from low to high pressure.
