ELUCIDATING NATURAL COLLOIDAL PROCESSES BY SINGLE-PARTICLE MULTI‐ELEMENT FINGERPRINTING WITH ULTRA‐HIGH FREQUENCY SPECTROMETRY

Nanogeosciences

The project targets environmental archives to investigate nanoparticles pertaining to events such as volcanic eruptions and anthropogenic pollution. We use multi-element and isotopically resolved single-particle analysis based on inductively-coupled plasma time-of-flight mass spectrometry to identify the sources of the nanoparticles. This involves highly explorative applications, such as the analysis of Pb-isotopic ratios in particles extracted from lake sediments.
The project is supported by Prof. Michael Strasser (Sedimentary Geology, University of Innsbruck) and Prof. Gunda Köllensberger (Analytical Chemistry, University of Vienna) with their respective expertise in lake coring and trace metal spectrometry.

The project is funded by the Emerging Field Grant 2017 of the faculty of Geosciences, Geography and Astronomy at the University of Vienna.
