Abstract

An ICP/AES owning a high resolving power is able to measure the isotopic shift in emission atomic lines for heavy elements such as uranium. U-235 and U-238 are therefore clearly separated and identified. Using this phenomenon, the transposition of isotopic dilution mass spectrometry method to the ICP/AES instrument allows to quantify, with accuracy and precision, the U-235 content of a solution. The method, named IDAES, is the first that combine isotope dilution method and ICP/AES measurements. In order to demonstrate the validity of the IDAES method, an IDMS protocol using a MC ICP/MS instrument, is also applied to determine the amount content of U-235 of the sample.
