Dear subscribers Re: Stability test of reference electrode One of the important properties of reference electrode is its stability during measurements or potential scan. How one can check its stability in a certain electrochemical system? One of the way is to use internal reference, for example ferrocene. However I am afraid that it will be involve in some chemical reaction with my electrolyte system as I replace it each time (I am doing some screening). In some cases the ferrocene may not be dissolved properly. Are there any other methods that I can use to test the reference stability?
