OREAS 780

OREAS 780 is a fluorine-certified reference materials produced from a blend of fluorite ore and host rock materials sourced from the Speewah project operated by Tivan Ltd. This CRM is intended for calibration and quality control of analytical methods quantifying fluorine (F) or calcium fluoride (CaF₂) in carbonatite-hosted fluorite systems. It replicates mineralogical and geochemical features of natural fluorite deposits.

OREAS 780 has been characterized using the following methods:

  • Borate Fusion XRF- Majors and some traces
  • F addon to fusion XRF package
  • F by ion selective electrode
  • 4-Acid – Full ICP-OES and MS elemental suites

Certified values for applicable analytes are operationally defined for each method, with results under OREAS ISO 17034 scope of accreditation.

Note: Analyte values are indicative only and may change when certified.
