Rare Earth Element Ore CRMs
The Rare Earth Element (REE) range of OREAS® certified reference materials includes 6 standards ranging 0.53 - 9.88% TREO and are available in sizes from 10 g sachet up to 1 kg jar.
Each CRM in the series contains up to 110 certified values and 50 indicative values that include REEs, majors and traces by fusion XRF, fusion ICP and 4-acid digestion. The materials are sourced from both a quarry comprised of weathered barren siltstone and from the Lynas Corporation’s Mount Weld Project in Western Australia.
Lithium, Graphite, Tin, Phosphate Ore CRMs
Our expanding portfolio of OREAS® Critical Mineral CRMs includes lithium (Li), carbon (C), tin (Sn), and phosphate (P₂O₅) ores, to support the exploration and mining of these essential resources. The mineralization styles include pegmatites and concentrates for Lithium, graphitic veins in granodiorites for Carbon, skarn deposits for tin and phosphatic limestone and chert deposits for phosphorus.
These materials are available in 10 g and 500 g pack sizes. Custom packaging is available on request. We are actively introducing new materials to our portfolio of critical materials by collaborating with global stakeholders to meet the evolving needs of both the industry and our clients.
