Abstract

An improved metal electrode for the determination of pH, P_O.sbsb.2 or P_CO.sbsb.2 in liquids is disclosed. The improved electrode consists of a metal sensor (e.g., antimony) in a holder characterized in that the metal is monocrystalline with only one plane crystal face exposed to the liquid.

Claims

1. An electrode for the measurement of pH, P_O.sbsb.2 or P_CO.sbsb.2 in liquids, including a metal sensor in an insulating holder said metal sensor having a surface adapted to contact said liquids characterized in that the said metal is monocrystalline manufactured and arranged to provide only one plane crystal face for exposure to the said liquid.

2. An electrode according to claim 1 wherein the metal is antimony.

3. An electrode according to claim 1 in the form of a rod.

4. In a method for the measurement of pH, P_O.sbsb.2 or P_CO.sbsb.2 in a liquid wherein an electrode is exposed to the liquid, the improvement comprising using as the electrode the electrode of claim 1.

5. In the method of claim 4 wherein the metal is antimony.
