Does anyone know of a commercially available source of certified reference materials (standards) for REE in the range of 100 - 50000 ppm total REE?

The OREAS ® range of certified reference materials (CRMs) are prepared entirely from natural ore materials sourced from deposits throughout Australia, Southeast Asia, North and South America and Africa. This includes refractory gold, gold occluded in silicates and other metals hosted in refractory minerals.

Mineralisation in the ore consists of a quartz-sericite-carbonate schist assemblage containing the sulphides arsenopyrite, pyrrhotite and pyrite. OREAS 209 is one of a suite of eight CRMs ranging in gold content from 0.340 to 9.25ppm. Analyte. Certified Value. 1SD. 95% Confidence Limits Low. 95% Confidence Limits High. Method.
