| Zusammenfassung |
| During the last few years the IAEA has performed works in several directions as following:
• Released IAEA-603 (replacement of NBS19) - this is primary Stable isotope Reference Material (RM) used for the VPDB 13C and 18O scale realisation,
• Released 6 isotopically enriched (in 2H and 18O) waters,
• Performed careful monitoring of LVEC’ property delta-13C value. This resulted in understanding that LSVEC needs a replacement.
• Taken part in characterisation of 18 new organic CRMs (together with Indiana University and USGS)
• Creating collaborations with metrology institutes – focus on metrological aspects of RMs,
• As a spin-off of the Technical Meeting on Stable Isotope Reference Materials (IAEA, Vienna 2014) the European EMPIR project aimed to create infrastructure to produce gas mixtures characterised in CO2 isotope composition has been established (NPL, UK and other metrological institutes).
The presentation will give details of these works and overview of the current status of RMs production and development. |
