    1. Scope

    Characterization of REEs in ores and refined REE ores, from PLOQ to 99.9999 wt/wt%

    Manufacturers need specified and thus characterized REEs and REMs to produce according specifications. Also minimizing unnecesarry inclusion of not needed REE is economic not viable and characterization can prevent this.
