FLOW TYPE ION-SELECTIVE ELECTRODE, ELECTROLYTE CONCENTRATION MEASUREMENT DEVICE USING SAME, AND AUTOMATIC BIOCHEMICAL ANALYZER

摘要

Provided is an electrolyte concentration measurement device that uses a reduced amount of liquid for measurement and makes it possible to significantly reduce retained sample liquid and to maintain the high measurement accuracy of conventional ion-selective electrodes while achieving a stable seal with no spaces during ion-selective electrode flow path connection. In a flow type ion-selective electrode, a seal material used in a flow path connection part can be adhered up to the vicinity of a flow path hole, there is a gap definition material for maintaining a prescribed gap between electrodes and preventing the seal material from being excessively crushed, and an electrode housing has a structure corresponding to the seal material so that the seal material can be aligned and held.
