I am biasing the reference electrode and working electrode of a potentiostat to perform amperometry and voltammetry. When performing measurements, I set the reference electrode potential to 1v and vary the working electrode potential.
However, I am not sure how to bias the electrodes in between measurements or when I am not taking measurements.
Can I set both electrodes to 0V?
Should I output high-z to the potentiostat for both electrodes?
How will the biasing of electrodes during rest affect measurements and what is the correct way to bias them?
Hello Jihong Min .
I am a little confused. Normally the working electrode is biased with respect to the reference electrode, with current flowing between the counter/auxilary electrode and working electrode in a conventional 3-electrode cell.
It is normal to allow the cell to sit at its open circuit potential (OCP) whilst at rest.
Could you provide any more information with regards to your electrochemical cell and the potentiostat that you are using.
Sorry, I just don't understand the purpose of biasing the reference electrode.
Hi
Have a look at

Hope this helps.
