Abstract
An improved electrode for use in oxygen determination is disclosed. Interference from carbon dioxide is eliminated by combining an improved electrolyte with means for permitting rapid electrolyte movement into and out of the space between the cathode and the membrane covering the cathode to maintain the pH of the electrolyte in the space substantially constant. The electrolyte consists of a KCl solution containing KOH of from 0.1 to 2%.
