Re: Simulating electrochemical reactions with Mathematica

DrHuang,

I didn't see Electrochemical Impedance Spectroscopy (EIS) listed as one of
the techniques supported by the Polarograph software. Correct me if I'm
wrong, but I don't think the conventional electroanalytical methods that
Polarograph lists will work in Ultrapure Water (UPW), where the resistivity
ranges from 1 to 18.2 Megohm-cm. My understanding is that a "supporting
electrolyte" would have to be added to UPW in order to use any of the other
methods. We cannot due this because we are interested in measuring the
characteristics of UPW that contains only very small amounts of contaminants
and adding an electrolyte would defeat the purpose.

Regards,
Nick
