Workshop
CCQM-GAWG Workshop on Carbon Dioxide and Methane Stable Isotope Ratio Measurements
- From 09 to 10
- October
- 2023
Task Groups
Terms of reference
- To carry out Key Comparisons, and where necessary pilot studies, to critically evaluate and benchmark NMI/DI claimed competences for standards and capabilities for gas composition (including binary and multicomponent mixtures); gas/liquid mixture composition; nanoparticle and aerosol concentration; isotope ratio measurement; concentration of dissolved gases in liquid or solid matrices;
- To assist in identifying and establishing inter‐laboratory work, pilot studies and research activities to provide SI traceable measurement results with reduced uncertainties for new measurement technologies in gas analysis such as dynamic dilution techniques for unstable gases, as well as spectroscopic techniques with the potential to be used as primary methods.
