Abstract
Novel methods for sample preparation by adapting an automated chromatography system to radiochemical analysis for analysis of trace impurities is reported. The methods were optimised with sample to sample times of 15–35 min. These samples were used to analyse 75 trace elements in uranium and plutonium and for the quantification of trace actinides. Uranium and plutonium samples were analysed with less than 4–7% relative standard deviation. The results were comparable with current methods for analysis and offer additional safety and efficiency benefits. The methods yielded a 20-fold reduction in sample size and a fourfold reduction in waste produced.
