Abstract
A method for regenerating an amperometric sensor involves bringing the electrodes of the sensor into contact with an active, complex-forming regenerating solution and connecting the electrodes into an adjustable electric circuit. This forms an electrochemical cell. Then, at least one negative and/or positive voltage pulse is applied to the electrochemical cell to either oxidize or reduce deposits on at least one of the electrodes into a deposit product, which is dissolved into the regenerating solution. The electrodes are removed from the regenerating solution and from the electric circuit, rinsed with a rinsing solution, and dried. After this, the electrodes are brought into contact with the sensor electrolyte and their functionality is verified. A device for performing this method is also provided.
