Circumventing Traditional Conditioning Protocols in Polymer Membrane-Based Ion-Selective Electrodes

Circumventing Traditional Conditioning Protocols in Polymer Membrane-Based Ion-Selective Electrodes Thumbnail


Abstract

Preparation of ion-selective electrodes (ISEs) often requires long and complicated conditioning protocols limiting their application as tools for in-field measurements. Herein, we eliminated the need for electrode conditioning by loading the membrane cocktail directly with primary ion solution. This proof of concept experiment was performed with iodide, silver, and sodium selective electrodes. The proposed methodology significantly shortened the preparation time of ISEs, yielding functional electrodes with submicromolar detection limits. Moreover, it is anticipated that this approach may form the basis for the development of miniaturized all-solid-state ion-selective electrodes for in situ measurements.
