AN286: Determination of Trace Copper, Nickel, and Zinc in Boiling Water Reactors Using Nonsuppressed Conductivity Detection

Instrument Type: IC

This work describes the determination of trace concentrations of copper, nickel, and zinc in a boiling water reactor (BWR) matrix (i.e., deionized water) by cation-exchange chromatography using a 2 mm Thermo Scientific Dionex IonPac SCS 1 column and nonsuppressed conductivity detection. A Thermo Scientific Dionex Ultralow Pressure Trace Cation Concentrator (TCC-ULP1) column is used to concentrate 8 mL of sample, which enables detection limits of <0.2 μg/L for copper, nickel, and zinc.

AU191: Determination of Trace Fluoride, Chloride, and Sulfate in Lithium-Containing Borated Waters

Instrument Type: IC

At nuclear power plants, monitoring the concentrations of trace anions is important to reduce the risks associated with operation and to maintain plant reliability. IC is the most popular technique for the determination of anions in power plant waters because it provides the required sensitivity to detect trace-level concentrations. This application describes a simple and robust IC method for the determination of trace fluoride, chloride, and sulfate in lithium-containing borated waters.
