hi!
I saw that you use to do more stripping step after one deposition step but after the first stripping the metal concentration in the surface is decreased, no? so the other peak will be referred to a lower concentration (that is the reason why the 2nd, 3th... are lower than the first, i think). How can you use these other values of current? do you use all this values and then do a average?
And i have another question: after the stripping how do you clean the electrode? Maybe here you are using a HMDE so you are 'new' electrodes for each experiment but in my case i work with a solid electrode so i need to clean the surface. Now i'm trying to clean simply by appling a positive potential but i'm not sure that is enough.
Thank you for your time and congratulations for the video :D

what is the working electrode that you have used, have you modified GCE
