Multi-gas sensor technology and respiratory gas analysis

Due to the high selectivity, we can also recognise unknown substances in complex gas mixtures in an exploratory manner. The particular strengths of this gas analysis are that the measurements can be carried out very quickly, continuously and without interruption, without contact, non-invasively, without labelling and on site at the point of care.

Highly sensitive Raman gas spectroscopy is therefore an extremely promising method for analysing gaseous and volatile biomarkers in exhaled breath and can be exploited for early, non-invasive disease diagnostics and therapy monitoring.

We also use isotopically labeled gases to disentangle specific biochemical pathways specifically and without background. By developing measurement techniques based on innovative microstructured hollow-core fibers and high finesse optical resonators, we achieve enormous signal amplifications. This enables us to detect even the lowest gas concentrations and quantify them robustly in the range from pure substances to trace gases.

With this highly potent gas measurement technology, we are research partners in various fields of medicine, life sciences, environmental sciences, renewable energies, etc.
