How to save on recurring cost of Certified Reference Materials and Working Standards

Certified Reference Materials are traceability-certified substances, supplied with a certificate of composition, that laboratories use for calibration and validation; because they cost far more than even high-purity reagents, many laboratories cut recurring expense by developing in-house working standards that remain traceable back to the original certified material.

Certified Reference Materials cost a fortune in comparison with even high purity reagents as they bear traceability to globally recognized standard bodies and are supplied with a certificate on their composition. A few mg or ml amount can cost as high as several hundred dollars.

Laboratories handling large sample loads can incur heavy recurring costs of certified reference materials. Mostly laboratories resort to use of working standards developed in-house which can be traced to the original certified reference materials.

Today’s lab bytes session offers an economical option for use of such materials.
