Electrodes
Counter electrode
– this electrode needs the least
maintenance of all. A quick visual inspection to ensure the
electrode has no physical damage.
Reference Electrode
– this electrode contains a liquid filled
tube, the liquid can be replenished by using the
Reference
Electrode Fill Solution
provided in the kit. Perform a visual
inspection to ensure it has no physical damage and ensure
there is enough liquid in the outer tube and that there are no
bubbles in the inner tube.
For best performance, the
Reference Electrode tip should be kept wet. Please remove
cap before use, and replace after use.
Always place a few
drops of deionised water in the cap before replacing it on the
electrode.
Working Electrode
–
the electrode surface should be
examined for cracks and imperfections that will affect analysis.
The electrode should be regularly polished to remove
contaminants and ensure a smooth mirror-like surface using
the supplied glass platen, polishing cloth and polishing slurry
(see below). Ensure that the protective rubber cap is replaced
during storage of the electrode to prevent damage to the
electrode surface. After polishing, conditioning steps need to
be undertaken before analysis. The different Working
Electrodes can be identified by the number of connecting pins
and are not interchangeable. Electrode WE1 (6 pins) is to be
fitted in position WE1.
Electrode WE2 (3 pins) is to be fitted in position WE2.
Do not mix up the electrodes.
