Cornelia Kriete - Federal Institute of Geosciences and Natural Resources, Hannover, Germany
Thomas Meisel - University of Leoben, Austria
- Discusssion of the latest practices for the production of “reliable” geochemical data that are associated with small measurement uncertainties.
- Provide an overview of current understanding of metrological traceability and the proper use of reference materials.
- Describe the role of measurement uncertainty and how it is affected by such issues as sample preparation, sample heterogeneity and data acquisition. Highlight the role of the IAG and its support of the geoanalytical community.
- Recent trends in sampling and sample preparation. Proper IUPAC terminology and recent ISO guidelines.
- Reference materials for quality control and method development.
- The role of proficiency testing within overall data quality assurance.
- The production of new certified reference materials.
