The mission of the OSL Analytical Laboratory is the support and development of educational and research activities in the field of Polar and Marine Sciences. With regard to the ongoing environmental studies, the laboratory focuses on the analysis of oceanographic, chemical, biological, and geological samples that are obtained during polar expeditions. During the last years the analytical facilities of the laboratory were gradually developed to meet the requirements of present-day science.

In addition to its analytical services, the OSL-Analytical Laboratoryis involved in various OSL qualification programs: It provides students hands on experience with state of the art equipment under the guidance of qualified instructors.

The following is a list of equipment and facilities that are used to conduct research at the OSL. These facilities are available to all members of the OSL network:


  • Optical Microscopy with Digital Imaging (Olympus BX60, BX50, SZX12, SZX9) for the analysis of geological and biological samples
  • Fluorometer (TD-700 and Trilogy, Turner Designs) for chlorophyll measurement in natural waters
  • UV-VISIBLE Spectrophotometer (SPECORD 200, Analytik Jena) for the quantification of Colored Dissolved Organic Matter (CDOM) in sea- and river water
  • Ion Chromatograph (761 Compact IC, Metrohm) for the cation/anion analysis of groundwater
  • Inductively Coupled Plasma Optical Emission Spectrometr (CIROS VISION ICP-OES, Spectro) for detection of trace metals in biological and geological samples
  • Automated Wet Chemistry Analyzer - Continuous Flow Analyzer (SAN++, Skalar) for measurements of dissolved nutrients (silicate, phosphate, ammonia, nitrite, and nitrate) in seawater
  • Elemental Carbon and Nitrogen Analyzer (Vario EL III, Elementar) to evaluate the accumulation of carbon and nitrogen in soil
  • Particle Size Analyzer (SediGraph 5100, Micromeritics) for the measurements of the grain-size spectrum of marine sediments
  • Voltammetry (747 VA, Metrohm) for the detection of ultratrace elements in seawater
