Demonstrating the comparability of certified reference materials

Analytical and Bioanalytical Chemistry, 2009
Certified reference materials (CRMs) enable the meaningful comparison of measurement results over time and place. When CRMs are used to calibrate or verify the performance of a measurement system, results produced by that system can be related through the CRM to well-defined, stable, and globally accessible reference(s).
