Abstract
PURPOSE:To make it possible to perform safe automatic cleaning for a long period without deterioration in electrode performance and without daily maintenance, by a constitution wherein hypochloride and surface active agent are added into sodium hydroxide having strong base property. CONSTITUTION:Gas partial pressure and ion activity in blood are electrochemically analyzed in an analyzer. In this analyzer, the blood sample which is picked out of a human artery is injected into a flow path, where electrode sensors 6-11 for measuring the concentrations of the components of gases or the components of ions are provided, through a sample injecting port 5. Thus concentration is measured. At the same time, an electrode cleaning liquid 3 and the mixed gas of oxygen and carbon dioxide are guided to electrode flow paths and the sample injecting port 5. The flow paths and electrode sensitive surfaces, which are contaminated with the blood sample, are cleaned. The cleaning liquid is composed of 0.01-0.1N sodium hydroxide having strong base property, 0.01-0.5wt.% hypochloride and 0.01-0.2wt.% surface active agent. These compositions act not to cancel the cleaning characteristics or disinfection characteristics of the reagent but to reinforce these characteristics. Deterioration in performances due to the potential drifts of the electrodes, carry-over and the like do not occur.
