Method Development for the Compound-specific Stable Isotope Analysis (CSIA) of oxygen isotopes in organic compounds

Stable Isotope analysis is a powerful tool in environmental research and forensics. In our research group we use it to elucidate the fate and degradation mechanisms of anthropogenic organic contaminants in the environment. Compound-specific Stable Isotope Analysis (CSIA) is established for several stable isotopes of interest (2H, 13C, 15N). Within the proposed thesis project we want to develop a new method for the analysis of 18O isotopes in organic compounds. One target contaminant of high environmental concern is MTBE (methyl tert-butyl ether) a former fuel additive and common ground water contaminant.

Scope of the study:
During the thesis, a new method should be developed and the final method should be validated by means of statistical methods. The data should be discussed and prepared for publication in a scientific journal

Methoden:
Measurement of 18O/16O isotope ratios by means of Gas Chromatography coupled to Isotope Ratio Mass Spectrometry (GC-IRMS). Laboratory work includes preparation of standards and fractionation experiments and their measurements.
