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.
