RE-7 Family: Electrodo de referencia no acuoso tipo tornillo

Descripción
∗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

Optional items (sold separately)
012108 RE-PV Preservative vial for reference electrode For preservation of OD 6.0 mm reference electrode
012057 RE-7 Teflon cap with Ag wire With Ag wire
012058 RE-7S Teflon cap with Ag wire With Ag wire
012176 Sample holder dia 6 mm (2 pcs) IPPG For double junction, manufacturing of the electrode
012177 Sample holder dia 9 mm (2 pcs) IPPG For double junction, manufacturing of the electrode
IPPG: Ion Permeability Porous Glass

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:

  1. 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.
  2. Before assembly the electrode, immerse and keep the IPPG; glass tip in an organic solvent for at least one hour.
  3. If bubbles are present around the IPPG; glass, remove with a slight tapping. Air bubbles will isolate, blocking the current flow.
  4. Use only high grade products and reagents.
  5. 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.
