Inductively coupled plasma mass spectrometry (ICP-MS) is widely used in inorganic analytical chemistry for element and/or isotope ratio measurements. The presence of interferences, which is one of the main limitations of this method, has been addressed in recent years with the introduction of collision/reaction cell devices on ICP-MS apparatus. The study of(More)
The experiments involved in the PHENIX french nuclear reactor to obtain precise and accurate data on the total capture cross sections of the heavy isotopes and fission products require isotopic ratios measurements with uncertainty of a few per mil. These accurate isotopic ratio meaurements are performed with mass spectrometer equipped with multicollector(More)
Two direct applications of a collision-reaction cell based Multiple-Collector Inductively Coupled Plasma Mass Spectrometer (MC-ICPMS) for the resolution of isobaric interferences are presented. The first one is the determination of <sup>90</sup>Sr/<sup>238</sup>U elemental ratio by double isotope dilution technique and the second one concerns the(More)
