Oxford’s Department of Earth Sciences Trace Element Research Facility provides an inorganic analytical service for accurate and precise measurements of many trace-level elements.
The facility contains two ICP-MS (inductively coupled plasma mass-spectrometer) instruments; a high performance quadrupole type 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. Both instruments have a wide linear working range that spans up to nine orders of magnitude and have unrivalled detection capabilities.
The facility provides 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 a chemical digestion technique. We can offer in-house digestion by a variety of digestion systems. Please see Trace Metal Concentration & High Precisions Isotope Analysis for more details.
