5 Methods, Models, Standards
Freitag, 09:00-12:00, H 36
Stable isotope methods have evolved into a versatile toolbox, which includes isotopic analysis of organic and inorganic samples, high-precision measurements of isotope ratios, and compound and position-specific analyses. This session focuses on advances in stable isotope methods, including the use of new instrument developments, the combined use of multiple isotopes, and modeling approaches such as Bayesian mixing models, isoscapes, and other novel techniques. Furthermore, we welcome contributions on the development and application of new reference materials and standards to ensure the accuracy and comparability of isotopic measurements. The session aims to provide an overview of the latest developments in stable isotope analysis and their applications in various fields, from ecology to geology, and to discuss future directions in this dynamic field.
Keynote: Dr. Sergey Assonov, formerly International Atomic Energy Agency (IAEA), Austria
