Applications

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.

[ 63 ]

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.

O₂ & CO

Combustion control in high temperature processes: O₂ and CO

Oxygen control enhances process and cost efficiency of incinerators. Oxidation requires excess air. But too much air cools down the combustion and increases the amount of CO in the flue gas. Real-time and in situ monitoring helps to optimize the oxygen content in combustion processes.

[ 157 , 154 , 3 ]

Combustion control in high temperature processes: CO

CO is a major element in high temperature processes. Optimizing CO concentration in flue gas increases combustion efficiency. Simultaneously, it reduces greenhouse gas emissions. CO detection at long wavelengths like 2.8 μm and 4.3 μm uses stronger vibrational absorption features than the shorter wavelength ranges. This effect increases the sensitivity of the detector and allows using measurement set ups with short path lengths.
