We are currently working on using a carbon electrode and cyclic voltammetry to develop a sensor, and we are using a MIP (O-PD) polymer to detect PFOA (our current target). Comparing our results with those in the literature, it's working, but we are unable to extract defined numerical data: in some cases, the peak of the curve is simply represented by the potential reversal point. For this reason, we are having difficulty in defining a baseline and a possible peak height. We have considered to use peak currents, but we detect many within the scan and we don't have a standard method to discriminate them. How do you advise us to proceed to obtain standardized and repeatable measurements?

Furthermore, we have noticed that in some measurements, performing multiple consecutive scans (from 3 to 5), the potential reversal point continues to vary its position, indicating different currents each time (it oscillates by 0.25 uA per cycle). Can this be considered a problem?

Thank you for your help and attention, have a good day.
