Radio-isotope lab

Our laboratory is equipped for the determination of biogeochemical reaction and bacterial production rates with radio-tracer assays. One of the routinely performed measurements in the radio-isotope lab is the quantification of methane turnover (i.e., aerobic/anaerobic methane oxidation rates) using 14CH4- and C3H4-amended incubations of water and sediment samples.

Responsible: PD Dr. H. Niemann

Equipment:

  • Oxidation furnace (Carbolite)
  • Purge and trap set-up for 14CO2 collection
  • Wet scintillation Counter (Perkin Elmer AS 2000)
