Abstract
Methods and systems for identifying contamination of an electrochemical sensor (10) and cleaning the electrochemical sensor (10) are provided. A method may comprise scanning the sensor (10) for the first time using CV to generate a reference set of readings; scanning the sensor (10) for the second time after the sensor (10) 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 (10) potential has shifted; scanning the sensor (10) for the third time to clean one or more elements of the sensor (10); scanning the sensor (10) 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 (10) has shifted due to pollution of the sensor (10), and/or that the sensor (10) can be further cleaned.
