Certified Reference Materials (CRMs)

We offer a wide selection of CRMs to help the laboratory analyst achieve superior analytical results.

Certified Reference Materials and Accreditation:
Analytical measurements depend on many variables to provide the credible data needed to make informed decisions. The quality of this data is only as good as the reference material used to calibrate the measurement device. High quality reference materials are available only from organizations with a robust quality system. Accreditation to ISO/IEC 17025 and ISO Guide 34, also called Double Accreditation, represents the pinnacle of quality system achievement and allows the credible production and testing of Certified Reference Materials (CRMs).
Sigma-Aldrich has four Double Accredited sites producing CRMs: Fluka (Buchs, Switzerland); Supelco (Bellefone, PA, USA); RTC (Laramie, WY, USA); and Cerilliant (Round Rock, TX, USA).
