(III) Measure
Now that the settings have been defined, we can start the measurement. Simply click the “Measure”
button and watch the electrochemical reaction in real time. If the cell has been prepared correctly and the
appropriate settings used, you should see a plot similar to that in
Figure 9.15
. Please note, you can stop the
measurement at any time by clicking the “Abort” button. However, if a measurement is aborted part way
through, you may need to clean the working electrode to remove any material which has built-up there.

The cell and electrodes should always be thoroughly rinsed immediately after each experiment with the
solvent that was used in your electrolyte. Always set the cell to dry, preferably in an oven, before you prepare
your electrolyte. This helps reduce contamination of your solution.
9.5 Maintenance
Finally, withdraw the tubing or needle used to degas the cell until it is no longer in the solution, so that it does
not interfere with the measurement.
