By using SVC-3C oxygen-free Voltametry cell, researchers can get rid of influence of oxygen in the cell by bubbling nitrogen gas, and also run the experiments at low temperatures.
For low temperature measurement, three special attention need:
1. Fluctuation of temperature-dependent reference electrode potential.
2. Increase of the solution resistance due to a decrease of supporting electrolyte salt solubility.
3. Incorporation of condensation of water vapor.
Using SVC-3C Voltammetry Cell:
1. Reference electrode is setting away, using sample holder.
2. Micro electrode is used to allow for a measurement in high resistivity solution.
3. This cell is closing.
