6.3 Rotating Ring and Disc Electrode (EAD)The rotating ring and disc electrode is connected to a bipotentiostat (association oftwo PGZ potentiostats). See chapter 6.2.or consult the Help file, keyword index:Getting started with a bipotentiostat.The use of a rotating ring and disc electrode is illustrated by the demonstrationexperiment “Detection of Cu(I) using a rotating ring and disc electrode”.Files:Bipotentiostat.EXPBipotentiostat005.CRVBipotentiostat011.CRVA +244 mV offset has been automatically applied to the experimental files in orderto obtain their potential quoted versus SHE. The half potential calomel electrodeused as reference is +244 mV/SHE [2].6.3.1 AbstractA 10 mV/s linear voltammetry is operated on the disc electrode from +400mV downto -600mV (versus the reference electrode) while the potential on the ring electrodeis set at +400mV (versus the same reference electrode) in order to detect Cu(I).156VoltaLab 21/06/10/40/50/80Section 6, Chapter 3: Rotating Ring and Disc Electrode (EAD)
