Applications

CO₂ & NOx

Emission control of exhaust fumes: CO₂ and NOx

Guided by environmental policies, the automobile industry is concerned to reduce the carbon footprint of vehicles. Automotive suppliers develop innovative combustion engines to control CO₂ and NO_x concentration in exhaust fumes.

[ 115 ]

NOx

Monitoring of breath gas: NOx

The field of breath analysis considers NO_X as a biomarker for asthma and other pulmonary diseases. This new technology becomes more established for clinical applications. It is a cost-effective and non-invasive method of diagnosis and treatment monitoring.

[ 116 , 49 ]

NOx

Emission control of flue gases: NOx

NO_x is produced during fuel combustion at power plants and other industrial facilities. When it reacts with SO₂ it causes acid rain. For this reason NO_x and SO₂ emissions are restricted and need to be monitored.
