TY - JOUR A1 - Kipphardt, Heinrich A1 - Czerwensky, Michael A1 - Matschat, Ralf T1 - ICP-MS analysis of high purity molybdenum used as SI-traceable standard of high metrological quality N2 - The need, concept and technical approach for the certification of SI-traceable standards of high metrological quality for chemical analysis of the elements is briefly explained. As an example of problems occurring in the certification of these standards, special technical aspects related to the analysis of high purity Mo by ICP-MS, namely blank reduction for Na, Li and Ni by protective coating of the cones with silicon, as well as dealing with the interferences from the Mo matrix, are discussed.
