1. 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.
