Reference electrode using local environment ph control (United States Patent)

Inventor: Nathan Lawrence

A reference system for an electrochemical or ion selective sensor where a reference electrode is coupled with a redox active species and the redox active species is configured to set a pH value of a local environment of a low buffer/low buffering capacity analyte media proximal to the reference electrode. The pH value of the low buffer/low buffering capacity proximal to the reference electrode may be controlled to a pH value at least one pH unit above or below pH 7. The voltammetric response of the redox active species is used as a reference and/or reference signal for the electrochemical or ion selective sensor.
