Certified Reference Materials (CRM's) A CRM is a reference material, characterised 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 uncertianty, and a statement of metrological traceability.

Certified Reference Material (CRM) is the main quality standard within a laboratory's analytical routine. With it, it is possible to verify

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:

Rocklabs certified reference materials for platinum, palladium and gold are available in four solutions. These are PK3, PG04, PD05 and PD06. Each material is available in sachets of 30 and 50g and jars of 2.5kg. The materials are used to produce high-quality products in platinum and palladium refining and trade. 2. Au and Ag Oxides

Certified Reference Materials (CRMs) are the materials that are characterized to an acceptable standard in terms of identification, 

A buffer is one of the best methods of achieving pH stability without interfering with the underlying process. Buffer solutions do in fact occur naturally; an example can be found in our own bodies, as our blood needs to maintain a pH of 7.35 to function properly. This basic premise is harnessed by reference material manufacturers to create

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