Laboratory for Hydrogeochemistry

The hydrogeochemical laboratory offers a range of methods for the analysis of essential elements, ions, molecules and sum parameters for the characterization of liquid and solid samples from aquatic geosystems

Ion analysis (IC) (IC)

  • Anion chromatography (conductivity detection with chem. suppression)
  • Cation chromatography (conductivity detection)

Spectrophotometry and Potentiometry
  • Laboratory and field photometer (Unicam and Hach) for nutrient and ion analysis
    (among others PO4, Si, NO3, NO2, NH4, H2S)
  • PC-controlled titration system for alkalinity

High pressure liquid chromatography (HPLC)
  • Ternary gradient system with fluorescence and UV detection for amino acid analysis
  • Ternary gradient system with amperometric detection for sugar analysis

Elementary analysis (CHNS)
  • Multiphase carbon analyser
  • CNS elemental analyser

Site analysis
  • CTD probe (wired or solid state storage, up to 100 m water depth)
  • Various multimeters (pH, conductivity, oxygen)
