ICP-MS Trace Element Analysis Facility

Oxford’s Department of Earth Sciences Trace Element Research Facility together with the School of Geography and the Environment provide an inorganic analytical service for accurate and precise measurements of many trace-level elements.

The facilities contains three ICP-MS (inductively coupled plasma mass-spectrometer) instruments; two high performance quadrupole types (PerkinElmer NexION 350D and NexION 2000B) that can routinely measure large batches of samples for a wide selection of trace elements, plus a high resolution magnetic sector type that is able to couple high sensitivity performance for ultra-trace concentration detection with high resolution power for interference-free analysis. All instruments have a wide linear working range that spans up to nine orders of magnitude and have unrivalled detection capabilities.

ICP-MS

The facilities provide a service to measure many sample types, including geological, archaeological, biological, plant and chemical matrices. Samples that contain significantly high matrix loadings may require extra preparation using chemical digestion techniques. We can offer in-house digestion by a variety of digestion systems. The School of Geography and the Environment’s inorganic sample preparation facilities allow for the dissolution of a wide range of sample types prior to analysis via ICP-MS. These methods include traditional hotplate digestions, phase extractions and microwave-assisted dissolutions. The Department of Earth Sciences also has a Biological Sample Preparation facility which offers microwave digestion of organic rich sample matrices.
