Application Note: Checking silver, platinum and gold electrodes
3 December 2019

It is essential to know before starting analysis if your electrode is in a good state or not. A good electrode will increase the quality of your results, as the accuracy and precision will be increased. Furthermore, tedious error tracking can be omitted and no sample will be wasted due to a defective or old electrode. There are several ways to check metal electrodes, e.g., measurement of redox potentials, potentiometric titration or bivoltammetric titration. This bulletin describes the best methods using electrodes available from Metrohm.
