AB108: Determination of Phosphite in Electroless Nickel Plating Bath

Instrument Type: IC

Electroless nickel plating relies on a reducing agent, such as sodium hypophosphite, to deposit nickel phosphorous on the surface of an item. Over time, the hypophosphite in the bath will oxidize to phosphite. This Application Brief uses an IonPac AS17 column and a Regent-Free IC system to determine phosphite in an electroless nickel plating bath.

AU133: Saccharin in Electrolytic Nickel Sulfate Baths

Instrument Type: IC

Saccharin decreases the tensile strength of electrolytic nickel deposits and can, with increasing concentrations, cause compressive stress. Determination of saccharin by ion chromatography is faster and has fewer interferences than classical titrimetric methods of analysis.
