Alloy Geek Rare Earth Element Reference Material - Low

AG-REE-LO | REE Containing Carbonatite Sample | Prepared 32mm XRF Sample Cup Unlock high-confidence trace element analysis with the Alloy Geek Rare Earth Element Reference Material - Low Concentration, derived from a carbonatite-based ore and certified under ISO 17034 standards. This material, also designated AG-REE-LO, is engineered for applications requiring precision calibration of analytical instruments like XRF. This low-level REE material features a light rare earth oxide concentration of 0.35 wt%, with values determined through WD-XRF (with Li-borate fusion), ICP-MS, and ICP-OES techniques. It is ideal for laboratories seeking robust quality control, method validation, and trace rare earth calibration in geochemical and industrial applications. Key Features: Certified Reference Material (CRM) – Produced under ISO 17034 accreditation Homogeneous Powder Blend – Based on carbonatite ore and Georgia-sourced CaCO₃
