Jai Ghosh

The answer is very simple. It is because glassy C electrode and Platinum electrodes are least affected by any chemicals present in most plant extracts.

you can not have Pt/Pt or C/C electrodes for this type of experiment. It is because one is the working electrode and the other is the auxiliary electrode.

Dear Prof. Ghosh, I am not electrochemsist so could you please give me more explanation about the choice of the couple glassy carbone/Pt wire for voltammetry cyclic tests of plant extracts. May I use Pt/Pt in my work?

Thank you very much in advance.

Richa Paliwal

GC/Pt is mostly preferred due to its higher negative as well as positive potential range, which can easily determine the compounds peak in preferred wide range.
