Determination of zirconium isotope composition and concentration for nuclear sample analysis using Thermal Ionization Mass Spectrometry
Alexandre Quemet, Christophe Maillard and Alexandre Ruas
A new Thermal Ionization Mass Spectrometry (TIMS) analytical procedure was developed to measure with high accuracy the zirconium isotope abundance and concentration without molybdenum correction in nuclear samples. This zirconium abundance determination methodology was used on three nuclear samples. Then, the calibration of a 91Zr spike solution was performed by reverse isotope dilution using a SPEX standard zirconium solution. The zirconium concentration determination was then performed on the three nuclear samples by isotope dilution using the SPEX standard zirconium solution and the 91Zr spike solution. The final uncertainties were estimated to be lower than 1%.
