Feature Article


Reference materials serve a critical function in analytical testing by establishing a standardized basis for measurement or value assignment. ISO Guide 30 defines a reference material as a “[m]aterial or substance one or more of whose property values are sufficiently homogeneous and well established to be used for the calibration of an apparatus, the assessment of a measurement method, or for assigning values to materials” [1]. A Certified Reference Material (CRM), according to ISO Guide 34, is a “reference material 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” [2]. For manufacture of active pharmaceutical ingredients, the US Food and Drug Administration (FDA) defines a primary reference standard as a “substance that has been shown by an extensive set of analytical tests to be...
