Isotopic ratios of molecular gases like the 13C/12C ratio in atmospheric air, biological processes or industrial emissions provide important information about the sources and sinks of several materials, or about their origin. Metrological traceability of isotope standards in the form of gas mixtures is currently being discussed. The PTB participates in the EMPIR project SIRS, that deals with the development of stable isotope standards and their metrological characterization. Our focus is on the metrology for mass spectrometric (WG 3.11), as well as IR-spectrometric (WG 3.22) methods for the determination of 13C/12C ratios in atmospheric CO2.
