摘要： 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.

摘要： An electrode system for measuring oxygen gas in a solution comprises a pair of electrodes consisting of an indicator electrode and a reference electrode immersed in an electrolyte solution and a membrane pressed against the indicator electrode. On the other side of the membrane, is a solution to be analyzed. In determination of gas in solution especially in blood, good reproducibility of data, a stable reading and a long performance life are obtained by rubbing the surface of the indicator electrode and rotating a magnetic stirrer on the membrane. These effective measures prevent the electrode and the membrane from being contaminated. Accordingly, continuous analysis of arterial blood can be achieved.
