Certified Reference Materials for Calibration and Method Validation

Reference materials are substances having homogenous and well-established values of one or more properties. They play a vital role in ensuring accuracy of measurements through method calibration, validation of a measurement method, estimation of measurement uncertainty, or assigning values to materials.

They are a critical component of analytical testing workflows and broader quality assurance schemes. Manufactured under stringent requirements, reference materials differ from other lab reagents in their certification and traceability of the data provided. The world of reference materials is vast and includes Certified Reference Materials (CRMs) and other quality grades of reference materials and concepts like certificates of analysis and metrological traceability.
