Reference Electrode

The reference electrode (RE) should have a diameter of 0.51 mm

(0.02 in). It will sit within the electrolyte but will not contact the

working electrode (sample).

Counter Electrode

The counter electrode (CE) is typically made from platinum-iridium

wire (Figure 149). It should encompass as much of the inner rim of the

liquid cell as possible. It may be useful to make the diameter of the

electrode slightly larger than the diameter of the cell, so that the

electrode will hold itself in place against the walls of the cell.
