Abstract: The electrochemical sensor system includes a capillary and a conductive wire at least partially disposed within the capillary. The wire is provided as a plurality of wires, such as a pair wires. The plurality of wires is disposed substantially parallel within the capillary. The wire extends from a first terminal end of the capillary to a second terminal end of the capillary. Where the wire is provided as a plurality of wires, the capillary includes a capillary wall separating the plurality of wires. The first terminal end of the capillary includes an electrode surface where the wire is disposed therethrough and is exposed, thus forming an electrode. The exposed wire is configured to form a liquid-air interface where a droplet is disposed on the exposed wire. The wire extending from the second terminal end of the capillary is coupled to a processor configured to perform the electrochemical analysis.
