A surface area analyzer measures the specific surface area of powders and porous solids by gas adsorption, using the BET method. The lower limit is 0.01 m2/g. Automated sample preparation reduces manual handling before each run. Real-time data display shows adsorption and desorption as the test proceeds, and a data storage system keeps results for later review. Pore size distribution can be calculated with the BJH method. Time-dependent adsorption studies are also supported. Pharmaceutical, catalyst and nanomaterial labs use these analyzers. Teams working on activated carbon, carbon nanotubes, graphene and other powders use them for research and quality control.
