Ion Selective Electrode

Ion Selective Electrode

An ion-selective electrode (ISE), also known as a specific ion electrode (SIE), is a transducer (or sensor) that converts the activity of a specific ion dissolved in a solution into an electrical potential, which can be measured by a voltmeter or pH meter. The voltage is theoretically dependent on the logarithm of the ionic activity, according to the Nernst equation. The sensing part of the electrode is usually made as an ion-specific membrane, along with a reference electrode. Ion-selective electrodes are used in biochemical and biophysical research, where measurements of ionic concentration in an aqueous solution are required, usually on a real time basis.

Ion Selective Electrode - Interferences
... The most serious problem limiting use of ion-selective electrodes is interference from other, undesired, ions ... No ion-selective electrodes are completely ion-specific all are sensitive to other ions having similar physical properties, to an extent which depends on the degree of similarity ... Most of these interferences are weak enough to be ignored, but in some cases the electrode may actually be much more sensitive to the interfering ion than to the desired ion, requiring that the interfering ion be ...
