ChemMaster and BET Sorptometer

ChemMaster has been designed as a versatile tool to investigate and extract information about surface chemistry and surface structure, which are important for design production, and application of a catalytic material. The PMI’s ChemMaster measures the quantity of adsorbed or desorbed molecules allowing determination of these characteristics, all measurements are done quickly with high repeatability. Further BET Sorptometer is also provided to extend the surface area measurement capability for variety of materials. PMI’s BET Sorptometer is fully automated, volumetric gas sorption analyzer to measure accurately adsorption and desorption isotherms for the characterization of surface area, pore size distribution, pore volume and pore structure of microporous and mesoporous materials, as well as the kinetics of adsorption.
