Ion-selective potentiometry enjoys practical utility as a simple analytical technique to
measure ionic constituents in complex samples. Advances in the field have improved the
selectivity and decreased the detection limit of ion-selective electrodes (ISEs) by orders of
magnitude such that trace analysis in micro and nanomolar concentrations is now possible
with potentiometric sensors. This tutorial reviews the fundamental principles of ion-selective

Ion-selective potentiometry enjoys practical utility as a simple analytical technique to measure ionic constituents in complex samples. Advances in the field have improved the selectivity and decreased the detection limit of ion-selective electrodes (ISEs) by orders of magnitude such that trace analysis in micro and nanomolar concentrations is now possible with potentiometric sensors. This tutorial reviews the fundamental principles of ion-selective potentiometry, describes the practical considerations involved in the use of these sensors to measure real samples, and discusses the statistical evaluation of experimental results compared with alternative analytical techniques.
