Small organic molecules

The BIPM coordinates an ongoing series of comparisons to support and benchmark NMI technical capabilities for content assignment of pure compounds and calibration solutions. It has a dedicated laboratory facility to support these activities, which are essential for realizing traceability and high accuracy chemical measurements. The comparisons run by the BIPM are an integral component of the CCQM and the Organic Analysis Working Group (CCQM-OAWG) overall strategy to enable NMIs to demonstrate their measurement capabilities in the area of organic analysis, and their basis for metrological traceability.
