ABSTRACT:
An improvement to the coated wire electrode has been accomplished via inclusion of a fortiophore into a sensor device. Sensor devices of the present invention include: an internal reference element; a membrane; and a fortiophore. Fortiophores are neutral charge carriers, which complex reversibly a corresponding ion of the conductive material used as the internal reference element. The fortiophore provides an electrochemically defined and reproducible solid internal contact between the membrane and the internal reference element. This solid internal contact, for example, in ion selective sensors, provides more reproducible potential offsets and better precision, and faster wet up. The fortiophores can be utilized in other electrochemical devices.
