Abstract
The system includes a wash source configured to concurrently generate a plurality of streams that are each incident on a sensor structure configured to detect a presence and/or amount of a compound on the sensor structure. The sensor structure has electrodes on a substrate. The wash source generates the streams such that each one of the streams is incident on a different one of the electrodes. Each of the streams is incident on one of the electrodes at an angle that is non-perpendicular to the sensor.
Claims22
A sensor wash system, comprising:
- a sensor structure having multiple electrochemical sensors on a substrate, the sensors each being configured to detect a presence and/or amount of a compound on the sensor,
- each of the electrochemical sensors including multiple electrodes,
- the electrodes in each electrochemical sensor including a working electrode to which compounds are bound such that a portion of the compounds are specifically bound and another portion of the compounds are non-specifically bound;
- a wash source concurrently generating a plurality of streams, different streams are each incident on a different one of the working electrodes such that the different streams each removes non-specifically bound compounds from the working electrode that receives the stream while leaving specifically bound compounds bound to the working electrode that receives the stream.

A method of operating a wash system, comprising:
- concurrently spraying streams of a wash liquid onto a sensor structure having multiple electrochemical sensors on a substrate,
- the sensors each being configured to detect a presence and/or amount of a compound on the sensor,
- each of the electrochemical sensors including multiple electrodes,
- the electrodes in each electrochemical sensor including a working electrode to which compounds are bound such that a portion of the compounds are specifically bound and another portion of the compounds are non-specifically bound,
