Chemisorption Analyzers

Chemisorption or chemical adsorption is the phenomena whereby chemicals bond strongly to surface of a material via ionic or covalent bonds. It differs from physisorption, where chemical attach to the surface of a material by weak Van der Waals forces. Although it can be difficult to differentiate, the convention is that chemisorption is present if the binding energy per atom or molecule is above about 0.5 eV. chemisorption is of particular importance to catalysts.
