3.
Use the banana cables and crocodile clips to connect the sockets on the front of the
Potentiostat to the appropriate electrodes.
I.
The red socket connects to the working electrode.
II.
The black socket connects to the counter electrode.
III.
The blue socket connects to the reference electrode.
4.
Start the Ossila Cyclic Voltammetry software. The window shown in
5.
Enter the appropriate settings for your experiment into the software (explained in more
detail in
Section 9.2
6.
Click the ‘Measure’ button.
I.
The system will sweep the potential between the working electrode and reference
electrode, whilst measuring the current between the working electrode and
counter electrode, in the follow steps:
Start Potential
→
Potential Vertex 1
→
Potential Vertex 2
→
Start Potential
II.
This will be repeated for the specified number of cycles.
7.
If
‘S
ave After Measurement
’
is turned on, the measurement data and settings will be saved
once the sweep has completed.
