Metabolomics
Electrochemistry
Redox biochemistry takes a central position in biological processes. Not only enzymes, but also hundreds of small metabolites are electrochemically active, thereby reflecting the redox status of a given biosystem and, even more important, dynamic changes within this system. > more
LC/MS
The coupling of high performance liquid chromatography and mass spectrometry (LC/MS) has become one of the most powerful tools for the analytical chemist since the mid 1980s. Electrospray ionization (ESI) und atmospheric pressure chemical ionization (APCI) allow for both the transfer of the HPLC eluent into the gas phase and the ionization of the analytes. > more
Ion Mobility Spectrometry
The diagnosis and assessment of the sanitary and environmental risks resulting from the presence, the mobility and the fate of volatile organic compounds (VOC) in contaminated soils, undergrounds, groundwaters or old landfills, need an accurate knowledge of their transport dynamics inside and between the several media of the natural environment. > more
GC/MS
For a certain identification of single compounds in complex mixtures the coupling of the capillary gas chromatography with mass spectrometry -shortly GC/MS - is the method of choice. > more
