Application and Development of Isotopic and Inorganic Mass Spectrometries in Chemical Metrology

This report summarizes the application and development of isotopic and inorganic mass spectrometries in chemical metrology. Isotopic and inorganic mass spectrometries play an important role in chemical metrology. They are applied in determination of chemical standard data, such as atomic weights and isotopic abundances, and preparation of isotopic certified reference materials and spikes. Absolute determination method of isotopic abundances and isotopic dilution mass spectrometry method have the metrological characteristic, which have being used in research of chemical metrology.
