Hi everyone,
I have a query about impedance measurement, I hope you would help me with this. It must be quite simple but I have almost no experience on the impedance
measurements.
The three electrodes system I employed, platinum working and counter electrodes and Ag/AgCl reference electrodein 75% H3PO4, connected to a standard potentiostat (it has fra). I filled measurement condition as follow: "10kHz to 0.1Hz with 106 frequency. Keep 0.5 V which is the rest potential." I started collecting data then its very unstable at initial 10 data points in Ohm vs. Ohm plots. Is it normal or lack of instrument's ability ?
How could I estimate the solution resistance with this?
