What internal standard should I use for electrochemical characterisation (CVs) in MeCN with a graphite electrode?

16 December 2019 1 7K Report

With glassy carbon, I've been using the Fc/Fc+ redox couple as an internal reference, since I'm using an Ag/Ag+ reference electrode. However, with a graphite electrode surface, Fc/Fc+ doesn't appear to cycle too well. What other standards are available that cycle well with graphite for organic cyclic voltammetry?

My redox substance has a potential of around 0.8-0.9V vs. Ag/Ag+
