Standards to differentiate CO2 emission sources in the atmosphere Standards and methods to calibrate instruments that measure isotope ratios of carbon dioxide in air and operate in the infra-red, have been described in a recent publication in Analytical Chemistry. Promoting traceability in laboratory medicine: new JCTLM website launched A new website launched by the JCTLM is aimed at increasing the understanding of metrological traceability and its impact on the consistency of test results in laboratory medicine. Reference measurement systems for novel biomarkers Methods developed at the BIPM for characterizing primary calibrators for the measurement of hepcidin, a major iron metabolism regulator, have been published in Analytical and Bioanalytical Chemistry. 2017 BIPM-EURAMET "TC Leadership" course Eighteen participants from 12 EURAMET member countries have successfully completed the BIPM-EURAMET "TC Leadership" course. The training they received will enable them to become more effective in their involvement in the CIPM MRA. It will also allow them to make personal contributions in their possible future work as Technical Committee (TC) Chairs or in supporting the Chairs in CIPM MRA related matters.

The BIPM's mission and role:

The mission of the BIPM is to ensure and promote the global comparability of measurements, including providing a coherent international system of units for:

  • Scientific discovery and innovation,
  • Industrial manufacturing and international trade,
  • Sustaining the quality of life and the global environment.

The unique role of the BIPM enables it to achieve its mission by developing the technical and organizational infrastructure of the International System of Units (SI) as the basis for the world-wide traceability of measurement results. This is achieved both through technical activities in its laboratories and through international coordination.
