PhD thesis, working title: "Two-dimensional chromatographic characterization of
dissolved organic matter from forest floor leachates and ground water."
Dissolved and colloidal phase organic carbon (DOC) plays an important role in the
carbon cycle and the formation of soil organic matter. It is a high diverse composition
of organic compounds and it consists, for example, of humic acids, fulvic acids,
phenols and amines. The amount and composition of DOC varies significantly as a
function of parent material and land use. Our point of interest hereby is do we see
any differences in the amount and composition of DOC at different landscapes and
soil depths. To investigate the distribution and composition of DOC, we obtained
dissolved organic matter (DOM) from forest floor, soil horizons and aquifers along a
land use gradient near Hainich national park, Thuringia, Germany. To explore the
DOC composition we use comprehensive two-dimensional gas chromatography (2DGC) with flame ionization detection. DOC is thereby chromatographically separated
along the molecular mass and the amount of functional groups. The resulting two
dimensional diagrams are then analyzed with image analysis and spatial statistical
tools to detect differences in composition and to identify patterns.
