Organic Geochemistry Laboratory

In the organic geochemistry laboratory the investigation of the quality, quantity and maturity of organic matter (F1) is one of the main tasks. The used methods are Rock-Eval pyrolysis (quality and maturity of organic matter; F2), gas chromatography (F3) and mass spectrometry (F4) (quality and quantity of organic matter). The latter method allows us to analyse specific biomolocules (biomarkers, e.g., n-alkanes, sterols (e.g., F5), highly branched isoprenoids, alkenones (F6). By these molecules we obtain detailed information about the sea-ice distribution (sea-ice proxy, IP25, F7) and the origin of the organic matter (terrigenous and marine biomarkers) as well as (paleo-) temperature, salinity, and productivity of the surface water.

The instruments for the above mentioned analyses are listed below.
