RDE stands for Rotating Disk Electrode, which typically consists of a rotating disk electrode made of materials such as glassy carbon, platinum, or gold. However, in your question, you mention RDE (PTFE), which may refer to a rotating disk electrode coated or modified with polytetrafluoroethylene (PTFE), a non-conductive material with excellent chemical resistance.

If you are using an RDE with a PTFE coating or modification, the sensitivity or sensing power of the electrode is typically determined by its electrochemical performance in a specific electrochemical reaction or sensing application. Here are some general approaches to evaluate the sensing power or calibration sensitivity of an RDE (PTFE) electrode:

It's important to note that the specific experimental conditions, analyte of interest, and the electrode's behavior will influence the calibration sensitivity or sensing power. Additionally, if you have a modified electrode with PTFE, the properties of the modification, such as thickness and coverage, can also impact the electrode's performance.

Thank you for your kind reply but I think this is a generalized answer not a specified one. please mention the analyte while checking the RDE sensitivity. Thank you in advance @Haresh Bhanushali
