Precautions
Electrode
This electrode is silver-silver ion reference electrode for non-aqueous solution.
In order to reduce the liquid junction potential, use the same solvent and supporting electrolyte, as a sample and electrode internal solution.
Solvent
The solvent in non-aqueous electrochemical should be considered as following:
- Electrode activity material and produced substance solubility.
- Select according to the potential area to be measured.
For example, dimethyl sulfoxide (DMSO) is major solvent in the negative potential area, and acetonitrile (ACN) is major solvent in the positive potential area.
The non-aqueous solution could contains impurities, and the impurities could cause the block reactions. Distilled the solvent sufficiently, to eliminated impurities before using.
Supporting electrolyte
If the sample is dissolved in an organic solvent, the supporting electrolyte must be added.
In order to select the supporting electrolyte, it is necessary to consider the following:
- Solubility in organic solvents
- Wide potential window
- No reaction with organic solvent
Typical supporting electrolyte:
- TEAP: Tetraethylammonium perchlorate
- TBAPF6: Tetrabutylammonium hexafluorophosphate
