Hi there, I am running an EIS experiment but I am missing a few components to running my experiment successfully. The experiment entails 2 stainless steel electrodes placed 1 cm apart in a potassium ferrocyanide solution, do an EIS sweep, and collect the nyquist and bode plots. What i am not sure of: How long do I need run the experiment for to collect sufficient data? and; what concentration of potassium ferrocyanide should I be using? I was thinking 0.1 M/L. Any help would be appreciated!
