When extracting peak currents in Cyclic Voltammetry, what processes does the baseline represent?

I know that when extracting the peak anodic/cathodic currents, it is typical to extract a baseline. I presume to account for non-faradaic processes (i.e. double layer charging), however I have not...

What does a peak current separation of >59 mV in a CV plot for a supposed reversible couple mean?

Hello, I using the ferri- ferrocyanide redox couple, and my CV plots show very good reversibility in terms of peak current ratios (ipa/ipc=1). However I am seeing peak separation values of 80 mV....

Why use a 3 electrode set-up for non-faradaic measurements?

What are the arguments of making a distinction between the CE and RE if I am measuring non-faradaic processes (i.e. binding events to a surface modified WE)? I understand the arguments for...

How does choice of Reference Electrode material affect the observed equilibrium potential of a redox couple?

Hello, so this is something that has been bothering me, and I can't seem to find the answer. I am running characterization CV experiments using the redox couple ferri-/ferrocyanide. My working and...
