1. Overview
Ossila’s Potentiostat is low-cost and easy-to-use system for performing cyclic voltammetry measurements.
Cyclic voltammetry is one of the most widely used electrochemical techniques, providing important
information about materials including:
• Reduction and oxidation potentials
• Reversibility of a reaction
• Electron transfer kinetics
• Energy levels of semiconducting polymers
The Potentiostat is capable of outputting potentials up 10 V, and measuring currents as low as 10 nA,
allowing for a wide range of material characterisation. The easy-to-use PC software included with the system
allows anyone to perform the measurement.

9.3.1 Taking a Measurement
1. Plug in and turn on the Potentiostat.
2. Use the cell connection cable to connect the Potentiostat to the same colour connectors on the
Test Cell Chip.
I. Red connector to WE1, 2, 3, or 4.
II. Black connector to CE.
III. Blue connector to RE.
3. Start the Ossila Cyclic Voltammetry software. The window shown in Figure 9.2 will open.
4. In the software enter the settings shown in Figure 9.11.
5. Click the ‘Measure’ button.

For the WE3 connector, if the Potentiostat is working and the measurement has been set up correctly, you
will see the response shown in Figure 9.12.
WE1 and WE2 will give responses that are the same shape as WE3, but with maximum currents of
approximately 30 nA and 100 nA respectively. WE4 is a simple resistor and will produce a straight line from
Figure 9.12. Example voltammogram for WE3 on the Test Cell Chip.
Here we will give an example on how to prepare a simple electrochemical cell to take a measurement of
ferrocene (Fc), which is the standard reference used for cyclic voltammetry.
(I) Before Starting
We recommend switching on the Potentiostat 30 minutes prior to use. This allows it to warm up and reach a
stable temperature, ensuring a stable measurement.
Furthermore, ensure that all apparatus, solvents and electrolytes are dry. This is because the presence
of water and its redox by-products may reduce the solvent potential window or react with the solvent or
analyte.
(II) Clean and Dry the Electrochemical Cell and Electrodes
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.
9.4 Performing Cyclic Voltammetry of Ferrocene
9.4.1 Preparing an Electrochemical Cell
21
(I) Start-up Procedure
Please allow 30 minutes for the potentiostat to warm up after turning on. Once warmed up, start the Ossila
Cyclic Voltammetry software. Ensure that the potentiostat is detected by the software. If it is, the “Connected
Systems” drop-down box will be populated, and the “Measure” button will be green. If there is nothing
in the “Connected Systems” drop-down box and the “Measure” button is greyed out, please refer to the
troubleshooting guide in Section 10.
9.4.2 Taking a Measurement
(III) Prepare the Electrolyte Solution
background electrolyte, but other electrolyte salts and solvents can be used. The solvent and electrolyte
choice are determined by the solvent potential window and the solubility of your analyte. Most electrolytes
are hygroscopic, so should be stored in a desiccator or inert atmosphere.
stir until the electrolyte has dissolved.
Secure the electrochemical cell with a clamp to ensure it is stable before adding the 20 ml of electrolyte
solution. Once dissolved, add approximately 10 mg of Fc to the solution and stir to dissolve it.
(IV) Set up the Electrodes
Place the cap on the electrochemical cell, then insert the working and counter electrodes into two of the
holes. We will now prepare the reference solution; a 0.01 M solution of silver nitrite in acetonitrile. Prepare
(V) Degas the Solution
Gently bubble inert gas through the solution using a thin tube or needle for approximately 10 minutes to
remove dissolved oxygen.
(VI) Connect the Potentiostat and Cell
Use the cable to connect the Potentiostat and electrodes. The connector colour corresponds to which
electrode it connects to:
• Red -> Working electrode
• Black -> Counter electrode
• Blue -> Reference electrode
