1. Sunday 30thAugust:
Quality Assurance in Analytical Geochemistry
M. Wiedenbeck, International Association of Geoanalysts

Pre-conference workshop at MAPT In conjunction with the 2009 MAPT conference, the International Association of Geoanalysts (IAG: http://geoanalyst.org) will be sponsoring a one-day workshop devoted to quality assurance and best practices for the analysis of Earth materials. The main focus of this workshop will be the analysis of silicates using both whole rock and micro-analytical techniques, though other fields of interest to the analytical geochemist will also be presented.

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 effected 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.

Input by workshop participants is most welcome. Participants wishing to present their work or who wish to have specific themes addressed should include this information at the time of registering.

Workshop Organizers: Michael Wiedenbeck, President of the IAG GFZ, Potsdam, Germany

2. Thursday, 3rd and Friday, 4^th September:
Applications and practical aspects of ion microprobe analysis

Lectures and practical demonstrations presented by the Edinburgh Ion Microprobe Facility (EIMF). Limited to a maximum of 20 places.
