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. During my studies, I focused on Environmental Chemistry and Ecotoxicology. For my diploma thesis I worked on GC-MS method development for the detection of volatile amines in the Bioorganics group of Prof. Dr. G. Pohnert in Jena.

At the Department of Isotope Biogeochemistry I will be working on method development of isotopic ratio measurements for my PhD. 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. Several established methods are available.
My aim is to improve and reduce operating expenses for the compound-specific isotope ratio analysis of organic compounds by means of online solutions.
