G. der Dillinger Hüttenwerke, D-6638, Dillingen/Saar, Federal Republic of Germany aut On the role of pure oxide materials for primary calibration and validation in inorganic bulk analysis [Elektronische Daten] [Gotthard Staats] Summary: Basic requirements are summarised for the application of primary pure compounds in inorganic bulk analysis, including those for quality assurance. Conditions for the minimum assay of the pure compound as compared to the repeatability of method and sample preparation are assessed as well as purity and assay requirements of pure analytes for sample matching with different calibration modes. The assessment of assays of pure Fe2O3, SiO2, CaCO3, Al2O3, MgO and Mn3O4 are given as examples. Suggestions are made for an universal system for the production and certification of pure compounds for use as primary references in inorganic bulk analysis.
