Independent Mineral Standards has been accredited for primary characterization of reference materials using a mass balance methodology during the materials preparation, rather than conventional multi-laboratory round-robin.
Gold concentrations are determined by precise gravimetric measurement of all input materials during CrushedCRM™ production. Total gold content is then established via measured masses, establishing metrological traceability independent of downstream analytical techniques.
This primary approach provides reference concentrations that are not subject to analytical recovery limitations, matrix effects, or calibration dependencies inherent in all assay methods. The methodology also offers independent validation for Chrysos Corporation PhotonAssay™ results through fundamental mass measurement principles.
The accreditation establishes an independent metrological traceability framework for gold analysis quality control applications.
