Regeneration method of ion-selective electrode, and ion-selective electrode and ion-concentration analyzer containing means adapted to practice said method
First Claim
1. A method for regenerating an ion-selective electrode equipped with an ion-selective membrane which is formed of a high polymer membrane containing an ion-selective material and plasticizer, which method comprises supplying to the ion-selective membrane a regenerating plasticizer which is either identical in every aspects or analogous in effects to the first-mentioned plasticizer and is capable of dissolving the ion-selective material therein and imparting flexibility to the ion-selective membrane.
