The selection of the correct reference electrode determines the quality for electrochemical measurement results and their lifetime.
High quality electrochemical measurements require a stable reference electrode potential and a low impedance reference electrode junction or frit. In contrast, inaccuracies in potential measurement due to an unstable reference electrode can cause erraneous results whereas a high impedance reference electrode frit in the range of several kΩ causes potentiostat oscillation.
