oxygen detecting agent, production method and oxygen sensing aqueous solution of oxygen detecting agent

摘要

high heat resistance, as well as a can be stored at room temperature, the ambient temperature and an object thereof is to provide a method of manufacturing the oxygen detecting agent and the oxygen detecting agent that can maintain excellent oxygen detection capability regardless. To this purpose, the oxygen detecting solution and an oxygen detecting agent is supported on a carrier, the oxygen sensing aqueous solution, ascorbic acid, and a stabilizer suppressing the oxidative decomposition reaction of ascorbic acid, the ascorbic acid and a redox dye to be reduced, as the stabilizing agent, to provide the oxygen detecting agent, characterized in that the use of rutin and / or rutin derivative. Also provide a suitable manufacturing method for the preparation of the oxygen detecting agent.
