Applications of potentiometry:

One of the most common and earliest applications of potentiometry is pH determination, and titration for the determination of electro active species. Through development of electrodes that selectively determine target ions, potentiometry in general is replacing many older, most expensive and time consuming method for analytically measuring and monitoring ion activity. Current developments in the ion selective electrodes (ISE) branch of potentiometry have made the monitoring of inorganic, organic, gaseous and biologically important ions possible. The flexibility in available configurations allows these ions to be monitored in a single sample solution (batch mode) or continuously in a flow through apparatus (flow-injection analysis).
