The determination of sodium using an ion-selective electrode is a relatively inexpensive and accurate method. It requires some skill and careful preparation to manage matrix effects. It is particularly sensitive with detection possible in concentrations less than 1 µg/l with meticulous care. We discuss sample collection through to measurement and analysis.
