Driven by decades of experience in gas sorption, the autosorb iQ series performs the most demanding measurements on non-, meso- and microporous materials with accuracy and precision. autosorb iQ is capable of determining specific surface areas (below 0.01 m 2 /g), active areas, pore volumes and pore size distributions (up to 0.35 nm) of porous solids in accordance with more than 20 ASTM, DIN and ISO standards. Determine standard testing methods. The autosorb IQ is your solution for the intelligent characterization of catalysts.
