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.

AN1088: Determination of Thiosulfate and Pyrophosphate in Crayfish Wash Powder

Instrument Type: ICMS

To make crayfish look more attractive to consumers, they are often cleaned with wash powder, and it is this wash powder that is suspected of causing the problems associated with excessive ingestion of crayfish. The reported harmful ingredients of crayfish wash powder are thiosulfate and phosphaterelated compounds. IC/MS was applied to the analysis of components in crayfish wash powder and an effective method was developed using the Thermo Scientific Dionex ICS-4000 Integrated Capillary HPIC System and the Thermo Scientific TSQ Vantage Triple Stage Quadrupole mass spectrometer.
