Instrument

  • Tescan TIGER MIRA3 FEG-SEM equipped with motorised backscatter electron and colour cathodoluminescence detectors, two Oxford Instruments X-Max 150 mm2 detectors and a WITec RISE Raman system.
  • Fully quantitative point analysis (Astimex 53 calibration), elemental mapping and mineral liberation analysis with Oxford Instruments Aztec software, correlative Raman mapping.

Samples

  • Holds 2 x 2.5cm round epoxy mounts and 1 x 2.5 cm x 7.5 cm thin sections or 4 x 2.5cm round epoxy mounts
  • Principally used for elemental analysis of polished thin section samples or imaging using BSE or CL detectors.
  • Examples of samples analysed include silicate minerals, tephra, sulphides, apatite.

Additional information
