The Isotropics Geochemistry Laboratory is a growing entity with new analytical techniques and services constantly being developed. We are able to offer research services for academic and industry-based projects. Please use our Enquiry Form if you are interested in discussing how we can help.
In Situ Analyses
- Major/minor element characterization by SEM-EDS and/or EPMA (some trace elements as well)
- Elemental characterization by LA-ICP-MS (spot analyses) in silicates, oxides (e.g. magnetite), sulfides, hard and soft biological tissues (e.g. vegetation, blood, bone); mapping possibilities upon discussion of needs
- U-Pb isotope dating of accessory minerals (e.g., zircon, titanite, apatite, monazite, rutile, garnet) and ore minerals (e.g., cassiterite, wolframite) by LA-ICP-MS
- Radiogenic Hf isotopes in zircon and rutile by LA-MC-ICP-MS
- Radiogenic Sr isotopes in carbonates and (bio)-apatite (COMING SOON)
- Radiogenic Nd isotopes in titanite, apatite and monazite (COMING SOON)
Solution-based Analyses
- Full chemical digestion of rock/mineral samples (HF/HNO3/HCl/H2O2), organic-rich materials (e.g. vegetation), biological materials (e.g. blood, soft/hard tissue) and aqueous samples. Microwave-assisted acid attack possible for all digestions not involving HF.
- Full major/minor/trace element characterization. Typically, sub-ppb trace metal detection limits
- Stable Ca, Fe, Cu, Zn (all sample types)
- Stable Mo and Nd isotopes using a double spike (rock/mineral; aqueous samples)
- Radiogenic Sr-Nd-Pb isotopes (all sample types)
- Isotope dilution Rb-Sr and Sm-Nd analyses (rock/mineral samples)
Geological Characterisation & Economic Resources
- Major/minor/trace element characterization via LA-ICP-MS in metals/alloys, oxides (eg magnetite) and sulfides (pyrite, chalcopyrite, sphalerite). Example analytical list for oxides/sulfides: Mg, Al, Ti, V, Cr, Mn, Co, Ni, Zn, Cu, As, Sn, Sb, Pb
- Major/minor element characterization via ICP-OES
- Minor/trace element characterization via Q-ICP-MS (SQ and TQ options)
- Stable Ca, Fe, Cu, Zn, Mo isotopes via MC-ICP-MS
- Rb-Sr and Sm-Nd (isotope dilution) analyses via MC-ICP-MS
- U-Pb isotope dating of accessory minerals (e.g., zircon, titanite, apatite, monazite, rutile, garnet) and ore minerals (e.g., cassiterite, wolframite) by LA-ICP-MS
Hydrogeochemistry
- Major/minor/trace element characterization in riverine, groundwater and marine samples
- Stable Ca, Fe, Cu, Zn, Mo isotopes
- Radiogenic Sr, Nd, Pb isotopes
- Stable Li, B isotopes (COMING SOON)
Biological Materials
- Major/minor/trace element characterisation in organic/biological media via (SQ/TQ)-ICP-MS (eg vegetation, blood/plasma, organic soft/hard tissue)
- Trace element quantification and/or mapping in soft/hard biological tissues via LA-ICP-MS
- Stable Ca, Fe, Cu, Zn isotopes via MC-ICP-MS
- Radiogenic Sr, Nd, Pb isotopes via MC-ICP-MS
