In the Organic Surface Geochemistry Lab (OSGLab) of the Geomorphology section, the smallest of molecules and isotopes open a door to the past. In the OSGLab we conduct research on regional differences of the causes and effects of past climate change and variations in biochemical cycles. In some projects, we can determine the "traces" of climate change down to a decade, in other projects biogeochemical processes are traced over millions of years.
In the laboratory, changes in the carbon …

The preparation laboratory includes facilities for the extraction of the soluble organic matter from sediments, sedimentary rocks, coals, microbial cultures and water samples using flow-blending-extraction and ultrasonic-extraction tools. Further, medium pressure liquid chromatography is used to separate extracts into different fractions of polarity (aliphatic, aromatic and polar NSO fraction).
