Mineral Sample Reference Material Production in the Center for Mineral Technology – CETEM
Certified reference materials play an important role in accuracy, traceability and comparability of chemical measurements. The demand for certified reference materials has been increased with the growth of the mineral activity in Brazil in recent years. At the present time, CETEM Certified Reference Material Program provides mineral sample reference materials and certified reference materials in conformance with guidance criteria issued by the ISO Advisory Committee on Reference Materials.
1. Introduction
Nearly every decision-making process in mineral research or industry depends on analytical data. Certified reference materials (CRMs) play an important role in accuracy, traceability and comparability of chemical measurements.
A CRM is a material, sufficiently homogeneous and stable with respect to one or more specified properties, which has been characterized by a metrologically valid procedure, accompanied by a certificate that provides the value of the specified property, its associated uncertainty and a statement of metrological traceability. Uses can include the calibration...
