Abstract
An amperometric sensor device for electrochemical determination of polyhydroxy and polyamine compounds in liquid chromatography and high pressure liquid chromatography in which use is made of an electrode formed of a substrate of transition metals having a surface layer formed of a multivalent oxide/hydroxide of the metal and in which the anionic vacancies in the coating are partially filled with halide or sulfide ions and/or in which cationic vacancies are at least partially filled with alkali metal ions.
