Combined silver ring electrode with a ceramic pin diaphragm.
The silver ring is coated with sulfide (Ag2S) for a higher sensitivity and a better limit of detection.
This electrode is well suited for precipitation titrations when the pH value varies (titrant silver nitrate) of, e.g.:
- chloride, bromide, iodide
- sulfides
- hydrogen sulfide
- mercaptans
- cyanides
c(KNO3) = 1 mol/L is used as reference electrolyte and storage solution.
