Electrode Connections
If you are using your MultiPort with a Gamry Instruments potentiostat, make the following connections to the
electrodes.
The Reference Electrode lead plugs into the white pin jack on the cell cable.
The green and blue leads from the cell cable are attached to the Working Electrode. Cell currents in a MultiPort
experiment are often large enough that you should clip the blue and green leads separately to the working
electrode.
The red lead on the cell cable clips to the Counter Electrode.
Make sure that the long black lead on the cell cable cannot touch any other cell connection. You may find that
connection of this lead to a source of earth ground, such as a water pipe, will reduce noise in your experimental
results.
If you are measuring very small currents, you may find that a metal enclosure completely surrounding your cell
will further reduce noise. In this case, connect the shield, known as a Faraday cage, to an earth ground. Then
connect the black lead from the cell cable to the Faraday shield.
Ga mry’s VistaShield is a versatile, easy -to-use Faraday cage that was designed to work well with the MultiPort
kit. When equipped with a Purge and Stir option, it provides a complete electrochemical corrosion test stand,
well integrated with Gamry’s cells, p otentiostats, and software systems.
Always double-check your cell connections. Even an experienced experimentalist will
occasionally leave one of the cell cable leads lying on the desktop.
Some potentiostats may not include a blue clip lead. In this case, connect only the green lead
to the Working Electrode.
