Ammonia is a gas that easily dissolves into water, there are several common detection methods,but ammonia is toxic and corrosive, the current measurement mainly uses the TDLAS direct measurement method. TDLAS is essentially a spectral absorption analysis technology, which uses the selective absorption characteristics of gas molecules for specific wavelength lasers, and analyzes the changes in the intensity of laser absorption to obtain the gas concentration. TDLAS spectroscopic absorption method can directly measure the concentration of ammonia gas, and can realize accurate measurement from % to ppb.

Why Ammonia Gas Analyzer is Important？
Application in environmental protection In metallurgy, coking, electric power, cement and other industries that use biomass as fuel, the process of removing nitrogen oxides from combustion flue gas and the importance of preventing environmental pollution have been acutely recognized as a worldwide problem brought it up. To remove nitrogen oxides (denitrification), the world’s more mainstream processes are divided into: SCR and SNCR. To run SCR and SNCR, the required medicines are ammonia and urea (the main reason for using urea is because it is kept for storage, and when used, urea is still cracked into ammonia for use). When monitoring the working efficiency of SCR and SNCR, the ammonia gas online analysis system must be used to control the consumption of ammonia water through the ammonia gas analysis system.
Denitrification process ammonia escape NH3 detection Flue gas denitrification refers to the reduction of generated NOX to N2, thereby removing NOX in flue gas. The more mainstream processes in the world are divided into: SCR denitrification and SNCR denitrification. SCR denitrification technology is a selective catalytic reduction method. In the presence of a catalyst (SNCR denitrification technology is a selective non-catalytic reduction method, in the absence of a catalyst and high temperature), ammonia gas decomposed from liquid ammonia or urea is used as Reducing agent, reducing nitrogen oxides in flue gas to nitrogen and water. Ammonia slip caused by the remaining reducing agent is inevitable in the reduction process. Escaped ammonia easily forms ammonium bisulfate with SO3 in the flue gas, such as ammonium bisulfate, which is highly adhesive, corrosive, and tar-like solids, causing corrosion, blockage, and dust accumulation in the air preheater, affecting the dust removal effect of downstream dust removal equipment and even causing damage; at the same time It means that the consumption of liquid ammonia/urea increases, which reduces the economical efficiency of the denitrification device; and the remaining ammonia gas will be discharged into the atmosphere to cause secondary pollution of the atmosphere.
Therefore, the detection of escaped ammonia in the denitrification process is very important for optimizing the control of ammonia injection and reducing pollutant emissions.

Here are some key advantages of using an ammonia TDLAS gas analyzer:
Measuring carbon dioxide (CO2) is important for understanding the role it plays in the environment and its effect on climate change. CO2 is a major component of Earth’s atmosphere, and it traps heat like a blanket, causing global temperatures to rise. Too m uch CO2 can lead to drastic changes in our weather patterns and ecosystems, so monitoring its levels is essential for predicting future climate conditions. Additionally, measuring CO2 can help us better understand our impact on the environment and make informed decisions about how to reduce emissions and slow down down down down down global warming. By analyzing CO2 data over time, we can develop strategies to mitigate the effects of climate change and ensure a sustainable future.
Before industrialization, the global average annual atmospheric carbon dioxide concentration was 278ppm (1ppm is one part per million). In 2012, the global annual average atmospheric carbon dioxide concentration was 393.1ppm. By April 2014 , the monthly average carbon dioxide concentration in the northern hemisphere atmosphere exceeded 400ppm for the first time. . 2. Global climate warming, the continuous aggravation of the atmospheric greenhouse effect leads to global climate warming, resulting in a series of global climate problems that cannot be predicted by today’s science. According to the International Climate Change Economics Report, if human beings maintain the current way of life, by 2100, there will be a 50% chance that the global average temperature will rise by 4°C.
