Abstract
An automatically depolarizing electrode system for analyzing ions and gases in a solution, especially in blood. A magnetic stirrer is placed in a test chamber of the electrode system and rubs the sensing surface of the electrode which constitutes the wall of the test chamber. During analysis, the rotating stirrer prevents blood from coagulating on the sensing portion of the electrode, so that the electrode is constantly kept clean and depolarized. Preferred is a flat and solid state ion selective electrode for this electrode system. Additionally, the size of the stirrer is designed not only to lessen the amount of a sample solution which is present in the test chamber but to prevent the reading response from retarding.
