New paper on U isotope analysis in the Journal of Analytical Atomic Spectrometry

Leja Rovan and Marko Štrok published a paper entitled “Optimization of the sample preparation and measurement protocol for the analysis of uranium isotopes by MC-ICP-MS without spike addition” in the Journal of Analytical Atomic Spectrometry. In their study, they  quantified the behaviour of uranium isotope ratios (²³⁵U/²³⁸U and ²³⁴U/²³⁸U) with different aqueous sample preparation and separation techniques using multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) measurements and optimization of the MC-ICP-MS measurement protocol to obtain high precision and accuracy for uranium isotope ratios. The obtained results were compared with reference values, and they show that different sample preparation and separation methods influence the uranium isotopic composition and consequently the final results of unknown samples.
