Research

Compound-specific Isotope Ratio Analysis (CSIA) development for online measurements of isotopic ratios of chlorine, bromine, sulphur and oxygen

My research interest is instrumental analytics with the focus on environmental applications.
At the Department of Isotope Biogeochemistry I am working on method development for isotopic ratio measurements and their application. Isotopic ratio measurements of natural samples can be used to identify and follow the distribution of organic contaminants e.g. in aquifers. Not only allows this technique to deduce contaminations to their origin, it also allows monitoring their attenuation in the environment. Our aim is to improve and reduce operating expenses for the compound-specific isotope ratio analysis of organic compounds by means of online solutions.
