Lithium, Graphite, Tin, Phosphate Ore CRMs
Our growing portfolio of OREAS® Critical Mineral CRMs now spans lithium (Li), carbon (C), tin (Sn), and phosphate (P₂O₅) ores, providing essential support for the exploration, mining, and analysis of these critical resources. These CRMs represent a variety of mineralization styles, including lithium pegmatites and concentrates, vein graphite within metamorphic gneiss, tin-bearing skarn, and phosphatic cherty limestone.
All materials are supplied in 10 g and 500 g pack sizes, with custom packaging available on request. We are actively expanding our portfolio, working closely with global stakeholders to introduce new critical mineral CRMs that meet the evolving demands of the industry and our clients, ensuring you have the tools to deliver reliable, high-confidence geochemical data.
Rare Earth Elements CRMs
The OREAS® Rare Earth Elements (REE) CRM series comprises fourteen Certified Reference Materials (CRMs) with TREO content ranging 0.03% to 8.84%, available in pack sizes from 10 g sachets up to 1 kg jars.
Each CRM in this series is comprehensively characterized, with up to 110 certified values and 50 indicative values, covering REEs, major elements, and trace elements, analyzed via fusion XRF, fusion ICP, and 4-acid digestion.
Our REE materials are sourced from clay-hosted (within phosphate/oxide mineral phases) deposits and carbonatite deposits both from Western Australia. These differing mineralization styles cover a diverse reference framework for research, method development, and interlaboratory comparison.
Research & Quantitative CRMs for Critical Minerals
Developed specifically for critical minerals research and analytical method development, this specialized suite of AnalytiChem-branded CRMs empowers laboratories, universities and research organizations to generate high-confidence, globally comparable geochemical datasets. OREAS reference materials are certified for specific analytical techniques, so the certified values inherently reflect the method employed. AnalytiChem reference materials, however, are certified using a combined quantitative technique approach, which averages across multiple quantitative methods to minimize technique-specific bias and produce certified values that are independent of any single method.
• Enable reproducible geochemical measurements across different laboratories
• Provide standardized reference benchmarks to support longitudinal studies
• Enhance data integrity through rigorously validated interlaboratory protocols
These CRMs set a new standard for scientifically robust reference materials, enabling researchers and analysts to push the boundaries of critical minerals science, advance analytical methods and deliver data you can trust, today and into the future.
