Workshops and Courses



Paris, France 13 August 2017


Reliability of geochemical data: How do we know?

The workshop runs 9:00 to 16:30 with lunch and refreshment breaks provided by the organisers. Course materials are also included in the registration fee of 135 euros.

Please bring your own laptop (or equivalent) with a spread sheet programme as some practical examples of measurement uncertainty calculations will be discussed.

Workshop Goals

  • Discuss 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

Specific Topics to be Covered

  • 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

The workshop will be given by Thomas Meisel, professor in Geochemistry in the Department of General and Analytical Chemistry, at the Montanuniversität Leoben, Austria. He teaches courses in aquatic chemistry, analytical geochemistry, analytical chemistry, etc. As a trained petrologist and analytical chemist and, as member of the ISO/REMCO (reference materials committee) as well as previous member of the certification advisory board of the IRMM, he understands the problems in earth sciences as well as metrological aspects of analytical chemistry. He has an extensive knowledge of TIMS, ICP-MS, XRF, INAA as well as in proficiency testing programmes, and has successfully lead several IAG quality assurance workshops at previous Goldschmidt conferences.
