CRMs

The accuracy of an analytical measurement is defined as the closeness of agreement between a test or measurement result and the true value. It usually requires calibration of the analytical method with a known standard. This is often done with standards of several concentrations to make a calibration or working curve.

The highest degree of confidence is achieved with Certified Reference Materials (CRMs), which are characterized by a metrologically valid procedure for one or more specified properties, accompanied by a certificate that provides the value of the specified property, its associated uncertainty, and a statement of metrological traceability, according to the definition stated in ISO Guide 30.

Cifga is the unique lab in the world with ISO 17034 accreditation as reference materials producer in marine biotoxins scope!
