Chemisorption is the process of forming chemical bonds from a chemical reaction between the substrate surface and an adsorbate. This chemical reaction alters the chemical structures at the surface of substrate (adsorbent). Chemisorption analyzers are typically used in the characterization of heterogeneous catalysts, where the catalysts and reactants are in different phases, towards activity, active sites and temperature dependent desorption, reduction, oxidation, and reactive behavior. Our equipment is ChemStar TPx™  by Quantachrome Instruments and is able to perform Temperature Programmed Reduction (TPR), Temperature Programmed Oxidation (TPO), Temperature Programmed Desorption (TPD), Pulse Chemisorption and dynamic BET analyses.
