The application of non-traditional stable isotope systems such as Mg, Si, S, K, Ca, Ti, V, Cr, Fe, Ni and Se in geochemistry, cosmochemistry and life sciences has been spurred by the advancement of the multi-collector ICP-MS (MC-ICPMS) over the last two decades.

In addition, the Sapphire can also be switched into Collision-Cell mode, where the ion beam is directed into a hexapole collision cell for the measurement of isotope systems where interferences cannot be resolved using high resolution, such as Calcium.
The Sapphire features high and low energy switchable ion beam paths that enable the user to operate the instrument as a traditional Multi-Collector ICP-MS with no compromise in performance. The collision cell capable instrument builds on the field proven Nu Instruments Multi-Collector ICP-MS platform (with over 170 installed instruments worldwide) to add unrivalled capabilities. Sapphire from Nu is a next generation Multi-Collector ICP-MS.
