Dionex is proud to announce a new method for determination of ionic impurities in nuclear power plants that use pressurized water reactors (PWRs). Application Note 250: Determination of Trace Nickel and Zinc in Borated Power Plant demonstrates how to minimize corrosion and Waters Containing Lithium Hydroxide Using Nonsuppressed Conductivity Detection reduce maintenance costs using an ICS ion chromatography system with an IonPac® SCS column and Chromeleon® Chromatography Data System software.

Corrosion is a major contributor to damage in PWRs, so lithium hydroxide is added to the primary water in order to combat the corrosive effects of the boric acid used to control core reactivity. Application Note 250 demonstrates a simplified method that uses cationexchange chromatography to determine trace concentrations of various transition metals. This approach minimizes the expense and time associated with preparation of the 4-(2-pyridylazo)resorcinol (PAR) postcolumn reagent currently used for this analysis.
