Cavity ringdown spectroscopy

Cavity-ringdown spectroscopy (CRDS) is an extraordinarily sensitive and enormously valuable tool for detecting trace concentrations of non-fluorescent molecules in the laboratory and in the environment. 

After his call to the new Chair of Marine Surface Chemistry and Physical Chemistry, the CRDS projects at CAU Kiel are continued at a very high level in the group of Prof. Gernot Friedrichs.
