Ion selective electrode, method for producing ion selective electrode and electrolyte analyzing apparatus

摘要

Problem to be solved: to stably fix an ion sensitive film having a hard adhesive as a base material on a support having a flow path of the test liquid.The ion selective electrode is formed by laminating the ion sensitive film 16 so as to cover the through-hole 18 after the elastic member 15 having the through-hole 18 corresponding to the opening 21 is laminated on the flow path of the test liquid and the support 11 having the opening 21 in a part of the passage.Since the angle formed by the side surface of the through hole 18 of the elastic member 15 with respect to the contact surface of the ion sensitive film 16 is in contact with at least 90 degrees, the ion selective electrode having excellent detection performance and long term stability stability can be provided.Diagram
