Hello,

I'm using Cyclic voltammetry in my lab. For checking my electrode's stability, I'm using multiple scan. (solution is Fe(CN)6 3-/4- 5mM in 10mM PBS and 0.1M KCl) My electrode is ITO (10 ohm/cm2), CE is platinum wire, RE is Ag/AgCl (sat' in NaCl)

But, in multiple or continuous scan, oxidation peak current is not stable. Even I didn't touch or clean my ITO, peak current is always different.

How can I understand this behavior? Will this difference make some noise on my experience? What can I do for reduce these noise?

Thanks.
