ICP-MS is a popular analytical technique for the determination of REE, from raw materials including soils, rocks and ores to impurities in highly refined rare earth products. The technique offers a fast multi-element REE detection at concentrations down to the parts-per-quadrillion (ppq) range. However, challenges often faced by scientists in REE measurement include the occurrence of polyatomic and isobaric interferences that are not resolved by quadrupole ICP-MS. Collision gases can be applied to remove polyatomic interferences. With its integrated Collision Reaction Cell technology, the PlasmaQuant PQ MS Elite offers an effective solution for such requirements. Furthermore sample preparation can also impose analytical constraints and must be considered in order to obtain accurate analytical data
