Chemical Laboratory

The chemical laboratory supports the scientific research at the ZMT with a broad range of analytical tools and a diverse set of laboratory and field equipment. The tackled scientific questions are related e.g. to element cycles, ocean acidification, identification of key compounds, degradation rates of metabolites and monitoring of environmental parameters.

The established routine measurements build the basis for the institute’s scientific research. Results provide information about e.g. amino acid composition, fatty acid profile, particle size distribution, micro nutrient content, isotope ratios (13C/15N/18O), and element content (e.g. organic carbon, total nitrogen, trace elements, including heavy metals). Special attention is put on waste management with focus on environmental protection.

The technical personnel participate in method development and in research expeditions. The technicians are engaged in the planning of field sampling to ensure best quality of the data.
