ChemMaster and BET Sorptometer
In stock
ChemMaster is designed as a versatile tool to investigate and extract information about surface chemistry and surface structure, which are important for the design, production, and application of catalytic materials. PMI’s ChemMaster measures the quantity of adsorbed or desorbed molecules, allowing determination of these characteristics. All measurements are performed quickly with high repeatability.
Additionally, a BET Sorptometer is provided to extend surface area measurement capability fora wide variety of materials.
PMI’s BET Sorptometer is a fully automated volumetric gas sorption analyzer used to accurately measure 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 adsorption kinetics.
PMI’s BET Sorptometer uses the same sample chamber for both micropore and mesopore analysis The same sample chamber is used for outgassing and testing.
