Certified Reference Materials (CRMs) ATCC Certified Reference Material is reference material which is homogeneous and stable with respect to one or more specified properties and for which traceability and values of uncertainty at a stated level of confidence are established, where applicable. To minimize the cost and difficulty, more practical means of performing such calibrations is to use transfer standards. If one has a single standard that is calibrated by a national laboratory, one can then transfer the "certified" accuracy by comparing the "certified" standard to the transfer standard for as many as three decades.
Starna UV/Vis and Fluoresence Certified Reference Sets Use these reference sets to easily validate your UV/Vis and fluoresence spectrophotometers. Each set is supplied with a certificate of analysis and NIST Traceability from our ISO and UKAS accrediated reference laboratory. Certified Reference Material (CRM) - 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.

Certified Reference Materials (CRMs) are ‘controls’ or standards used to check the quality and metrological traceability of products, to validate analytical measurement methods, or for the calibration of instruments.
A certified reference material is a particular form of measurement standard. Reference materials are particularly important for analytical chemistry and clinical analysis.
our society. Reference standards are used at all stages in the production process, and more than materials are available from LGC Standards. Raw materials Raw materials used in the cement manufacturing process include limestone, sand, shale, clay and slags.
The quality control of these materials is essential to the finished product. This chapter discusses the use of certified-reference materials (CRM).
can be used to link the measurement to this reference. Such CRMs can be compared to transfer standards, as they are known and used in physics, e.g. mass transfer standards.
Unfortunately, except for pure primary substances, such materials hardly exist in chemical. Stevensville, Michigan, Ap – Alpha Resources LLC has produced their first Ferrochrome Certified Reference Material, ARfor Carbon and Sulfur.
“Alpha Resources has not previously offered any Ferrochrome materials as a CRM; being our first, this is a notably high carbon which is not typically presented in other CRMs,” notes.
Reference material accompanied by a certificate, one or more of whose property values are certified by a procedure which establishes its traceability to an accurate realisation of the unit in which the property values are expressed, and for which each certified value is accompanied by an uncertainty at a stated level of confidence.
Many terms describe reference standards in analytical methods, like reference materials, certified reference materials, calibrator, standard, etc.
Certified reference materials are defined as reference materials characterized by metrological traceability, a certified value and an uncertainty budget. It complies with all requirements of ISOGLP, etc. and comes with complete documentation on.
