Equipment

• Stable isotope mass spectrometers (Isoprime) equipped with a gas bench/trace gas/CHN analyser/gas chromatograph for the determination of C/H/N isotopes on solids (sediments/carbonates/bacteria/plankton/terrestrial plants), single organic compounds like lipids and amino acids, and gases
  
  
• Gas chromatograph / Mass spectrometer for the identification of organic molecules
  
  
• Gas chromatographs (FID) for the determination of lipids, amino sugars, amino acids
  
  
• Gas chromatograph (FID, ECD, methanizer) for methane, carbon dioxide, and N₂O
  
  
• Gas chromatograph (FID) with fraction collector for the collection of lipids after separation on a GC column (mainly for ¹⁴C determination on single lipid compounds)
  
  
• High pressure liquid chromatographs (UV, Fluorescence, Diode array) for pigment and amino acid concentrations including fraction collector
  
  
• High pressure liquid chromatograph (electrochemical detector) for amino sugar concentrations
  
  
• Fluorescence spectrophotometer for the measurements of pigment concentrations
  
  
• CHN elemental analyser for carbon and nitrogen concentrations of solid samples
  
  
• TOC / TON analyser for liquid samples
  
  
• Microwaves for the extraction of organic material
  
  
• Two in situ-pumps (McLane) for filtering large amounts of water in situ down to 6000 m for collection of adequate amounts of organic material for organic geochemistry, isotope analysis, and molecular ecology
  
  
• Two freeze dryers for sample preparation
