Abstract:
1. A method for cleaning an electrode in a sensor, the sensor comprising a substrate, the electrode in contact with the substrate, and an electrolytic material in direct contact with the electrode, the method comprising the steps of: determining a measuring potential at which a concentration of a gas component is determined; applying a hydrating potential, the hydrating potential being a lower potential than the measuring potential in order to hydrate the sensor; selecting an oxidizing potential that is greater than the measuring potential; and applying the oxidizing potential to the electrode, the oxidizing potential between approximately 451 mV and approximately 649 mV, wherein the step of applying an oxidizing potential comprises: determining a time for applying the oxidizing potential based on at least one measurement of: wherein the step of applying an oxidizing potential further comprises taking at least two consecutive measurements across the electrode, wherein if these at least two consecutive measurements yield a value within 10% of each other over a measurement time period, oxidation and regeneration are considered complete.
