T1 - Gravimetric preparation and characterization of a primary reference solution of molybdenum N2 - Gravimetrically prepared mono-elemental reference solutions having a well-known mass fraction of approximately 1 g/kg define the very basis of virtually all measurements in inorganic analysis. Serving as the starting materials of all standard/calibration solutions, they link virtually all measurements of inorganic analytes to the purity of the solid materials they were prepared from. In case these solid materials are characterized comprehensively with respect to their purity, this link also establishes direct metrological traceability to The International System of Unit. Within the framework of the European Metrology Research Programme (EMRP), in the Joint Research Project called SIB09 Primary standards for challenging elements, a reference solution of molybdenum was prepared directly from the respective metal with a relative expanded uncertainty associated with the mass fraction of Urel(w) < 0.05 %. A highly accurate and precise ICP OES and MC-ICP-MS method was developed to assist with the preparation and as a dissemination tool.
