What does ISE stand for and what is the difference between Specific & Selective ?
Ion Selective Electrode?
ISE converts the activity of a specific ion dissolved in a solution into an electrical potential which can be measured. 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.
