ELECTROLYTE MEASUREMENT STRUCTURE, FLOW-TYPE ION-SELECTIVE ELECTRODE USING SAME, AND ELECTROLYTE MEASUREMENT DEVICE

WIPO Patent Application WO/2023/013257

A1

Provided is an electrolyte measurement structure that makes it possible to reduce the influence of sample liquid retention on measured values, carry out accurate measurement, and smoothly replace an ion-selective electrode.　This electrolyte measurement structure is capable of being connected to another electrolyte measurement structure via a sealing member and comprises a body 401 having a flow path 401a that passes therethrough, a fixing structure 404 that has a fixing recess for fixing a sealing member 405 to the body 401, and the sealing member 405. The sealing member 405 is an elastic body in which a sheet region and a protrusion region that is fixed by the fixing structure are formed so as to be integrated. When the sealing member 405 is fixed to the fixing structure 404 and the electrolyte measurement structure is not touching another electrolyte measurement structure, the amount of protrusion of a first location that is the location on the surface of the sheet region that protrudes the most is greater than the amount of protrusion of a second location that is the location on the surface of the protrusion region that protrudes the most.
