CAN118: Determination of Trace Sodium in Diesel and Biodiesel Fuel

Instrument Type: IC

Sodium determination in diesel fuel using inductively coupled plasma-optical emission spectrometry (ICP-OES) is possible; limits of detection are ~0.1 ppm. The goal of this study was to develop and test an alternate approach using IC for the determination of cations in diesel fuel. The approach focused on the use of commercially available modules and existing standard chromatographic conditions. The challenge was to design an automated, cost-effective, fast, and sensitive method that can provide 10–100 times greater sensitivity than ICP-OES method and does not require manual extraction steps.

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.
