More Information
Summary:The present invention addresses the problem of improving both ion-selective electrode stability and adhesion between a sensitive film and a frame. The ion-selective electrode is provided with: a sensitive membrane containing an ion-selective substance, a substrate, and a plasticizer; and a frame that holds the sensitive membrane, and the frame material containing a substance having a solubility parameter (SP value) of 19.5 to 21.5. 兼顾离子选择性电极的稳定性以及感应膜与框体之间的粘接性。本公开的离子选择性电极具有含有离子选择性物质、基体及增塑剂的感应膜和容纳所述感应膜的框体，所述框体的材料含有溶解度参数(SP值)为19.5～21.5的物质。
