The BELSORP MINI X can measure specific surface area/pore size distribution by volumetric gas adsorption technique. Microtrac MRB's unique dead volume evaluation method (AFSM) makes highly accurate and reproducible measurement free of environmental change. The analyzer measures up to 4 specimens simultaneously with the highest level of precision and reproducibility in the world and a drastic reduction in measurement time.
