Should I pretreat the electrodes?

Electrodes are ready to be used and no general pretreatment protocol is established. With screen-printed electrodes you avoid tedious polishing steps of conventional solid electrodes before performing a measurement.

Still, some researchers apply electrochemical pretreatments for specific applications. For example, the typical treatment of gold electrodes is preforming successive cycles in sulphuric acid (0.1M) between 0 and 1.6V at s.r. 100mV/s.
