I am studying Cyclic Voltammetry using screen-printed electrodes. However, I am observing a shift in peak potential each time. Kindly advise regarding the possible reasons for this and also strategies to minimise this shift.
In the conventional 3-electrode setup, I am using glassy carbon as working electrode, platinum as counter electrode and platinum wire as reference electrode. Can it be used in this configuration?...
