Certified Reference Materials are high-purity substances with accurately defined properties, used to calibrate analytical instruments and validate measurement methods. They are essential for ensuring the accuracy, reliability, and international traceability of laboratory results in industries ranging from steel production to mineral analysis.

Quality is at the core of our operations. Goodfellow Reference Materials, through its subsidiary Bureau of Analysed Samples (BAS), is proud to be a United Kingdom Accreditation Service (UKAS) accredited Reference Material Producer (No. 4004). We hold accreditation to ISO 17034:2016 for the production of reference materials and are certified to BS EN ISO 9001:2015 for our management systems.

To suit various analytical techniques, our materials are supplied in several formats:

• Finely divided (chips or powders): Primarily for chemical analysis (BCS-CRMs and EURONORM-CRMs).

• Solid (discs or blocks): Specifically designed for spectroscopic analysis (SS-CRMs).

• Setting-up Samples (SUS): Available for the daily calibration and maintenance of spectrometers.
