ELECTROCHEMICAL SENSOR HAVING A MEDIATOR COMPOUND

摘要

An electrochemical sensor, especially for gases, is provided having a mediator compound based on transition metal salts of polybasic acids and/or transition metal salts of polyhydroxycarboxylic acids. The electrochemical sensor also contains a DLC, BDD or a precious metal thin-layer measuring electrode ( 3 ). The electrochemical sensor may be used for determining SO₂ and H₂S.
