While we'd love to help, I'm afraid nobody at Pine Research is familiar with Biologic software to help with troubleshooting an electrochemistry problem. But, if you want to send us some data, we can take a look at it and discuss it during one of our livestreams where we do troubleshooting.
Hi. It was a very helpful video, thanks for the explanation!!!! I have a question though, how can someone find the R and C of our experiment? We need them in order to use the Cotrell plot.
This is a great question. In short there are many ways to calculate R and C. Electrochemical impedance spectroscopy is the most direct method, albeit the technique is complicated. I can go through the different methods on our Livestream episode #70 tomorrow.
Thanks for the comment...I replied to a similar comment you made on one of our previous Ask Us Anything About Electrochemistry livestreams. I promise I will answer this question for you on Friday during our next livestream, it will be episode #72 on 1pm EST this coming Friday, Oct 25.
Correct. Molecules need to diffuse towards the electrode surface to oxidize, but as the diffusion layer thickness increases, there are fewer and fewer molecules near the surface to oxidize and hence the current decays.

@@syedashobnam2573 Just to be clear, there is no such thing as "current controlled chronoamperometry." Chronoamperometry is by definition a potentiostatic technique where the potential is controlled and the current is measured. I assume the method you are referring to is "chronopotentiometry," which is where you control the current and measure the resultant potential. We will certainly keep this in mind and if we are able we will make a similar video on chronopotentiometry.
I'm getting lots of help from your video.Thanks
Very glad to hear, happy you enjoy our video content!
Very informative...thanks for your video about this topic 😊
You are very welcome. I hope it helps!
Great informative ❤
Glad it was helpful!
Can we get one of you help regarding errors in biologic software for electrochemical sensing

Hello thank you so much.. Please I need a tutorial on how to run chronocoulometry and calculate the effective surface area? Thanks
