"Improvements in the element specific analysis of environmental samples through development and application of new sample preparation techniques";
Technische Universität Wien, Fakultät für Technische Chemie, 2009.

Limitations of current analytical methods often prevent a detailed investigation of complex scientific tasks such as the determination of the composition of airborne particulate matter. In particular is the examination of emission, transportation and transformation of individual aerosol constituents in the environment often hampered by the severe problems of traditional analytical techniques (e.g. limitations in the accuracy due to specific and non-specific interferences). For example suffers the qualitative and quantitative characterization of major organic aerosol constituents from insufficiencies in the selectivity of conventionally applied methods. On the contrary is the assessment of the environmental and biological significance of certain trace metals often limited by the sensitivity of common element specific analysis techniques.
Thus there is a great demand for the development of improved analytical procedures (including sample preparation and analysis), which is the main focus of this Habilitation thesis. The presented work deals in particular with the development, optimization and application of new sample preparation strategies, which allow in combination with appropriate analytical detection techniques a better characterization of environmental samples.
