The Horiba SA-9600 flowing gas BET surface area is an instrument that measures the specific surface area and the pore size distribution of powders, solids, and granules. The specific surface area/pore size of a material is estimated from the amount of adsorbed/desorbed N2 gas in a relationship with its pressure at 77 K as described by BET theory. The values are expressed in meter square per gram.

This instrument can measure BET in the range 0.01 – 2,000 m2/g. Ideal for characterizing:

• MOFs,
• zeolites,
• metal oxides,
• activated carbon
• other catalytic materials
