Major & Trace element data added to 36 CRMs

The Certificates and their associated DataPacks for 36 pre-existing OREAS CRMs have been updated with over 72 new indicative (uncertified) values for major and trace elements determined by borate fusion XRF and laser ablation ICP-MS. This will further extend their utility and surpasses ISO Guide 31 recommendation in regard to, “the approximate composition of the material should always be stated.”
