Comb. Ag ring electrode with Ag2S coating

Comb. Ag ring electrode with Ag2S coating
Order number: 6.0450.100S

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.
