Kurzbeschreibung
The Nu Sapphire is a novel type of multi-collector ICP mass spectrometer with a double focusing geometry equipped with collision cell for ultimate control of the spectral interferences, especially in the light part of the mass spectrum. The Nu Sapphire at MU Leoben is equipped with 16 Faraday cups and 3 ion counters at the low mass end of the multicollector, and state of the art 1013 amplifiers for isotope ratio measurements of target elements at ultra-low levels. Cetac Aridus 3 and ESI ApexΩ membrane desolvation units are available for sample introduction under dry plasma conditions to further increase the sample sensitivity and minimize the oxide formation rate. A laser ablation unit is available for in situ isotopic analysis of solid samples.
The Nu Sapphire was installed in April 2021, and is being used to develop new analytical protocols and to setup novel isotope proxies to answer questions in the area of environmental, geosciences and other fields. Routine analysis of Sr, Pb and other systems are also being carried out.
