Familia RE-7: Eletrodos de referencia para solucoes nao aquosas
∗RE-7VN Non Aqueous reference electrode screw type was designed to be used in Allum / ALS brand flow cell, for this reason there is a possibility that it will not be compatible in another brand flow cell.
- For apply in an organic solvent sample
- Internal solution changeable
Preservation of the electrode
- Fill the sample holder with an acetonitrile/0.1 M tetrabutylammonium perchlorate/0.01 M AgNO3 solution.
- Rinse the Ag wire with acetone.
- Keep the electrode immersed in an acetonitrile/0.1 M tetrabutylammonium perchlorate solution, with or without Ag ion (0.01 M AgNO3).
Note:
- Avoid the dry of the IPPG (Ion Permeability Porous Glass); glass, it could cause the crash of the IPPG; glass tip, caused by the salt crystallization inside of the glass. Make sure to keep the tip always wet.
- Before assembly the electrode, immerse and keep the IPPG; glass tip in an organic solvent for at least one hour.
- If bubbles are present around the IPPG; glass, remove with a slight tapping. Air bubbles will isolate, blocking the current flow.
- Use only high grade products and reagents.
- Wash with acetonitrile. Salt crystallization, in the inner side of the Teflon cap and at the edge of the sample holder, makes difficult the assembly.
