The role of secondary discharge formation and the physical and chemical processes occurring in the supersonic expansion with respect to NdO+ formation are discussed.
In this new article Karla Newman of the Water Quality Centre at Trent University, Peterborough, Canada, reports on the relative elemental sensitivities for a number of sample and skimmer cone combinations. She looked at standard and enhanced pumping of the interface region for the Thermo Scientific Neptune MC-ICP-MS.
An improved understanding of the mass fractionation behaviour of Nd on different MC-ICP-MS instrument platforms is important for the application of Nd in geochronology and provenance studies and will also contribute to a wider understanding of the origins of instrumental mass fractionation in ICP-MS.
