The 14 naturally occurring rare earth elements, Sc and Y were determined in fusion solutions by inductively coupled plasma mass spectrometry with limits of quantitation similar to an acid digestion procedure. Two potassium-based fluxes (K2CO3 and K2B4O7) were studied as fusion media. To maintain the level of total dissolved solids within the range permitted by instrumental criteria, K and B were removed from the solution, thus avoiding the necessity for considerable dilution.

Abstract
The 14 naturally occurring rare earth elements, Sc and Y were determined in fusion solutions by inductively coupled plasma mass spectrometry with limits of quantitation similar to an acid digestion procedure. Two potassium-based fluxes (K2CO3 and K2B4O7) were studied as fusion media. To maintain the level of total dissolved solids within the range permitted by instrumental criteria, K and B were removed from the solution, thus avoiding the necessity for considerable dilution. The validity of the procedures has been verified by precision and accuracy tests on selected Standard Reference Materials.File in questo prodotto:
