In practice, the Certified Reference Material assists the analytical procedure in obtaining the sample value (quantitative) / identity (qualitative), being able to provide more precision, accuracy and traceability to an analytical process, enabling more reliable measurements and identifications. Check out some of the benefits:

Certified Reference Materials. The production and certification of these materials to the highest metrological standards is carried out by the IAG Certification Committee according to the IAG Certification Procotol [1, 2], which takes account of ISO Guides 34 and 35. Because of the variety of composition of geological materials, the

The certified mass fractions delivered by Standard Reference Material (SRM) 1270a are intended primarily for use in validation of chemical and instrumental methods of analysis for element contents of iron and steel alloys. They can be used to validate value assignment of a laboratory's in-house reference materials.

These certified reference materials (also known as standards) are used to monitor the accuracy of analyses reported by mineral testing laboratories.

Certified Reference Materials. Precise Formulations. Reliable Results. Customers rely on Tannas Company for precise formulations of reference oils and catalysts. Now we offer more reasons to purchase our laboratory materials, including:

requirements for the competence of reference material producers). The scope of accreditation comprises certified reference materials in the form of non-ferrous metals and alloys, ceramics and glass, soils and sediments, food, ethanol/water solutions, aqueous solutions of stable isotopes, lubricants and fuels as well as porous materials.

NIST supports accurate and compatible measurements by certifying and providing over 1200 Standard Reference Materials® with well-characterized composition or 

Descripción general. This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

Materials, produced as certified reference materials by the NBL Program Office, are distributed to participants as "unknowns." Labs submit results, and the NBL Program Office generates an evaluation report indicating degree of agreement with the certified values. Participation is open year-round.

In-house production of standards or the dilution of a solid reference material does not guarantee the quality of a reference material. A 

The National Research Council of Canada's (NRC) Metrology Research Centre prepares high-quality and reliable certified reference materials
