Abstract
Methods and systems for identifying contamination of an electrochemical sensor () and cleaning the electrochemical sensor () are provided. A method may comprise scanning the sensor () for the first time using CV to generate a reference set of readings; scanning the sensor () for the second time after the sensor () has been employed; comparing a second set of readings from the second CV scan to the reference set of readings; when the second set of readings is different from the reference set of readings, determining that the sensor () potential has shifted; scanning the sensor () for the third time to clean one or more elements of the sensor (); scanning the sensor () for the fourth time; comparing a fourth set of readings from the fourth CV scan to the second set of readings; and determining that the potential of the sensor () has shifted due to pollution of the sensor (), and/or that the sensor () can be further cleaned.
