The Agilent 8800 is a triple quadrupole ICP-MS with two quadrupole mass filters, separated by a quadrupole, acting as a collision/reaction cell. The target ions from the analyte are selected by the first Q1 and pass to the CRC, where ions are separated from overlapping interfering ions. Q2 then filters the resulting ions for the detector. The instrument today is mainly coupled to the Laser NWR213 and being used for the elemental analysis of solid samples.

Multi-Quadrupole ICP-MS, Multi-Quadrupole Inductively Coupled Plasma Mass Spectrometer (PerkinElmer, USA)
The PerkinElmer NexION® 5000 is a multi-quadrupole ICP-MS and is the first of its kind to boast four quadrupoles, which aid with meeting lower detection limits and background equivalent concentrations. The instrument is currently being used for measurements of elements with difficult isobaric interferences (e.g. Ga, Ge) where the use of tandem mass spectrometry is critical. It is also used for measurement of technology critical elements in environmental samples, where excellent detection limits are a distinct advantage.
The instrument is run within a strong collaboration with:
- PerkinElmer https://www.perkinelmer.com
- Solutions 4 Science https://www.s4science.at
- Service 4 Science https://www.service4science.at

MC ICP-MS
Multicollector inductively coupled plasma mass spectrometer (Nu Instruments Wrexham, UK)
Webpage: https://www.nu-ins.com/products/hr-mc-icp-ms/introductiontoicp-ms
The Nu Plasma HR is a multi-collector ICP-MS with a double focusing geometry equipped with 12 Faraday detectors and 3 ion counters situated at the low mass end of the collector.
Initially installed in 2006, the instrument is today being used above all for routine isotope ratio analysis (e.g. Sr, Pb), training purposes and experimental work.

Nu Sapphire
MC-CC-ICP-MS
Multicollector inductively coupled plasma mass spectrometer with collision cell
(Nu Instruments Wrexham, UK)
Webpage: https://www.nu-ins.com/products/hr-mc-icp-ms/sapphire
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.

Automating Sample Purification
prepFAST-MCTM (Elemental Scientific, Omaha, USA)
Webpage: https://www.icpms.com/products/prepfast-MC
The prepFAST-MC is a low pressure chromatography system and enabled fully automated loading of the sample onto a separation column, washing and final collection for precise isotopic analysis. This device was purchased in 2021 as part of the “Impulsprogramm des Rektorats zur Anschaffung von F&E Infrastruktur an der Montanuniversität in Leoben” and is primarily used for the Sr/matrix separation prior to isotopic analysis.
