Silver/Silver Chloride contamination of working electrode

If you are using screen printed electrodes, either made inhouse or from a third party you may find peaks near 0 V when you run a cyclic voltammogram. What you are seeing is the spillage/contamination of the working electrode by the ink/paste used to make your reference electrode.

 

If you have data that looks like that in the adjacent image then please contact Zimmer and Peacock for an explanation and  a fix.
