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
• Wide Elemental Range – Major, minor, and trace elements including Ce, La, Nd, Pr, Sm, Eu, Y
• Multi-Technique Compatible – Calibrate XRF, ICP-MS, and ICP-OES
• Shipped from the USA – Quick delivery with support from Alloy Geek
