Overview
The BELSORP MINI X is a compact analyser that records gas adsorption-desorption isotherms by the volumetric method. Measurements are typically performed with nitrogen at liquid-nitrogen temperature, with argon or carbon dioxide as alternative adsorptives and krypton available for low-surface-area samples. Multiple measurement ports allow samples to be analysed in parallel. From the isotherms the software derives BET and Langmuir surface area, BJH mesopore size distribution, t-plot and micropore analyses, and total pore volume. The BELPREP VAC III degassing unit removes moisture and adsorbed species before analysis by controlled heating under vacuum, which is essential for repeatable results. The system characterises catalysts, adsorbents, zeolites, MOFs, activated carbons, ceramic powders, battery materials and pharmaceutical excipients for product development and batch-to-batch consistency checks.
