USE OF A REFERENCE SYSTEM FOR ELECTROCHEMICAL ANALYSIS AND DEPOSITION METHODS

摘要

Use of a reference system for electrochemical analysis and deposition methods, in which analysis or deposition methods at least one operating electrode (21), a mating electrode (23) and a reference electrode (22) are used, wherein the reference electrode (22) is a pH electrode (10) that has an impermeable membrane (12), and an input amplifier V1 (16) for the pH electrode (10) having a high input impedance is provided, and supplies the signal from the pH electrode (10) to the input amplifier V1 (16) via a cable, and a further amplifier V2 (17) is provided, which is used to compensate for the disadvantageous effects of the screening and of the cable and of the test setup, or the amplifier V1 (16) is integrated in the pH electrode (10) as an impedance converter, or the amplifier V1 (16) is integrated in the connector of the pH electrode as an impedance converter.
