Combined silver ring electrode with fixed ground-joint diaphragm.
This electrode is suitable for precipitation titrations when the pH value varies (titrant silver nitrate) of, e.g.:
- Chloride, bromide, iodide
- Sulfides
- Hydrogen sulfide
- Mercaptans
- Cyanides
The fixed ground-joint diaphragm is insensitive to contamination and the permanently fused-in silver ring is resistant to more highly concentrated acids and saline solutions.
c(KNO3) = 1 mol/L is used as reference electrolyte and storage solution.
Depending on the application, we recommend using an Ag ring electrode with a coating (AgBr, AgCl or Ag2S coating), which can be ordered accordingly.
