CCQM Working Group on Organic Analysis (CCQM-OAWG)

Terms of reference

• To carry out Key Comparisons, and where necessary pilot studies, to critically evaluate and benchmark NMI/DI claimed capabilities and competences for the execution of "higher order" measurement procedures for well-defined organic molecular entities^* for which the SI traceable amount of substance is to be determined.
• To consider, on a selective basis, similar activities for high-priority method-dependent analyses/measures.

^*. "Organic molecular entities" are taken to exclude gaseous compounds, organometallic compounds, and large bio-molecules.
