Samples are prepared for further analyses in the lab of the research group Marine Geochemistry - a collaboration between the Max Planck institute for Marine Microbiology, Bremen, and the Institute for Chemistry and Biology of the Marine Environment at the University of oldenburg. The lab, led by Thorsten Dittmar, is home to the world’s most powerful ultrahigh-resolution mass spectrometer for marine research. Its analyses of molecular masses are precise enough to enable the assignment of molecular formulae –
or put more simply, to determine the number of atoms of elements such as carbon, hydrogen, oxygen and nitrogen that are present in a compound.
