Description
Complete Set of AG-REE-LO/MED/HI | REE Containing Carbonatite Samples | Prepared 32mm XRF Sample Cups
Upgrade your elemental calibration workflow with the Alloy Geek Rare Earth Element Reference Material 3-Pack, featuring all three levels—Low (0.29 wt%), Mid (0.74 wt%), and High (3.8 wt%)—of our carbonatite-based REE standards. Each sample is ISO 17034-accredited and designed for precision calibration of analytical instruments such as handheld and benchtop XRF.
This 3-pack covers a wide range of light rare earth oxide (LREEO) concentrations, enabling laboratories to build, test, and validate robust REE quantification methods with confidence.
What’s Included:
- AG-REE-LO — Low-Level REE (0.29 wt% LREE, 0.35 wt% LREEO)
- AG-REE-MID — Mid-Level REE (0.74 wt% LREE, 0.89 wt% LREEO)
- AG-REE-HI — High-Level REE (3.8 wt% LREE, 4.5 wt% LREEO)
Each sample includes a sealed container of fine powder with full ISO-accredited certification.
Key Features:
- ISO 17034 & ISO/IEC 17025 Accredited Reference Materials (RM)
