    Abstract: A miniature probe contains multifunctional electrochemical electrodes which measure the hydrogen ion activity or pH of samples. One of these electrodes is contained within a carbon dioxide sensor while the other electrode can be coupled with a separate reference electrode, which may, if desired, surround the probe thereby providing a hydrogen ion activity or pH sensor. In this manner, the miniature probe contains a carbon dioxide sensor and a pH electrode, or a carbon dioxide sensor and a pH sensor.

    Abstract: A bicarbonate ion electrode is described which has an electrode lead, an electrochemically active region of silver and a silver halide other than a fluoride at one end thereof, an electrolyte containing at least the bicarbonate ion to be detected and an ion which enters into electrochemical equilibrium with the active region of the lead in contact with the active region, a hydrogen ion permeable membrane encapsulating the active region and the electrolyte, and electrical insulation covering the remaining portion of the electrode lead. When the potential of the electrode is measured with respect to that of an external reference electrode, a bicarbonate ion sensor is provided.
