Chemisorption is the process of chemical bonds forming from a chemical reaction that alters the chemical structures at the surface of one or both chemical reactants involved. In nature, chemical reactions often form with the help of a catalyst that lowers the activation energy of the reaction. Chemisorption analyzers allow scientists to characterize catalysts which can then be used for synthetic chemical reactions and play important roles in fuel quality and energy industries. Chemisorption analyzers can also be used to analyze particle size and surface area. Chemisorption analyzers can either measure chemical reactions exclusively or be sold as a unit that performs physisorption analysis as well.
