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.
