Performance evaluation of indigenous amperometers for the determination of uranium

The performance evaluation studies of three indigenously manufactured amperometers were carried out for uranium determination in U3O8 standard solution. Three analysts independently carried out ten determinations each of uranium by Biamperometric end point detection method with each of these amperometers. Two-way ANOVA test was performed on the data using MATLAB-7.0 software to test whether the variation in the observed data is statistically significant. No significant bias in the data produced by three analysts with three independent instruments was observed. The results obtained show that the indigenous amperometers are suitable for uranium determination in fuel materials and for nuclear material accounting, with high precision and accuracy.
