CO
Monitoring of breath gas: CO

The relatively new research field of breath analysis defines CO concentration in exhaled breath as a biomarker for e. g. respiratory infections and asthma.

CO
Early fire detection: CO

Early fire detection technologies rely on highly sensitive detection of carbon monoxide. Coal-fired power plants, steel mills or biomass deposits use these smoke detectors to increase process and workers safety.
