Combustion control in high temperature processes: CO₂ and CH₄
Continuous monitoring of contents like CO₂ or CH₄ concentrations is essential for the efficiency of high-temperature processes in e. g. incinerators, furnaces or petrochemical refineries. Managing the CO₂ content in combustion processes simultaneously reduces greenhouse gas emissions. This is also relevant for energy generating industries like coal burning power plants. [12, 35, 40, 45, 62, 94, 96, 112, 113, 116, 122, 125]

Quality control in natural gas pipelines: CO₂
CO₂ is a natural diluent in oil and gas deposits. When it reacts with H₂S and H₂O steel pipelines corrode. Real-time monitoring of CO₂ at natural gas custody transfer points is necessary to avoid contaminated gas from flowing downstream. Immediate measures may be taken to purify the natural gas. [116]

Emission control of greenhouse gases: CO₂
Environmental policies have been implemented worldwide to reduce greenhouse gas emissions. According to the United States Environmental Protection Agency, human activities account for more than three quarters of CO₂ emissions. They are mainly due to the combustion of fossil fuels for energy generation, transportation and industry. Remote sensing technologies have been introduced to quantify CO₂ and CO emissions in atmosphere. [93, 106, 116]

Monitoring of breath gas: CO₂
Helicobacter pylori bacteria cause stomach ulcer. Breath analysis diagnoses such an infection in a non-invasive way replacing disagreeable gastroscopies. It uses the CO₂ concentration in exhaled breath as a biomarker. [9,88, 116]

Emission control of exhaust fumes: CO₂ and NO_x
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. [116]

Emission control of exhaust fumes: CO₂
Remote sensing technologies identify unclean vehicles on the road. They help to control traffic-generated carbon dioxide emissions. [116]

Isotope detection by NASA Mars Rover Curiosity: CO₂ and H₂O
NASA’s flagship Rover Curiosity detects CO₂ and H₂O isotopes based on their tunable laser spectrometer SAM. The analysis of soil samples is to determine whether Mars is or has been a suitable living environment. We are proud that the instrument uses a 2.78 µm nanoplus laser for this measurement. [25, 116]

Surveillance of volcanic activities: CO₂
Early warning systems for volcanic eruptions continuously monitor CO₂ by TDLS, as it is an abundant volcanic gas. [116]
