Nitrogen pentoxide analyzer

Nitrogen pentoxide analyzerOnline measurement based on cavity ring down spectroscopy technology (NO3/N2O5). Select a laser with a center wavelength of 662 ± 1nm and two optical resonators composed of two sets of high-power mirrors. The first chamber directly measures NO3 radicals; The second chamber measures the sum of NO3 and N2O5 (where N2O5 is converted to NO3 by heating), thus achieving real-time measurement of NO3 and N2O5. It can also be combined with other gas analyzers, such as sulfur dioxide (SO ₂), nitrogen oxides (NOx), etc., to achieve comprehensive monitoring and control of various pollutants.

NO3 radicals are key species in atmospheric chemical reactions, and for certain volatile organic compounds (VOCs) (especially terpenes), dimethyl sulfide (DMS), and olefins, the oxidation ability of nitrogen trioxide even exceeds that of daytime OH radicals. In addition, it also plays a key role in the non photochemical conversion of nitrogen oxides NOx (NO/NO2) in the atmosphere to HNO3 and the formation of nitrate aerosols. Given the crucial role of NO3 radicals in atmospheric reactions, accurate measurement of their concentration levels and variation patterns is of great significance for studying nighttime atmospheric chemistry. Due to the high reactivity, short lifespan, and extremely low concentration of NO3 radicals, accurate measurement is challenging.

Nitrogen pentoxide analyzerApplication fields:

1. Atmospheric environment monitoring: It can measure the concentration of nitrogen pentoxide in the atmosphere to evaluate air quality, understand atmospheric chemical processes, and provide data support for air pollution control.

2. Industrial emission monitoring: In some industrial processes, such as the production of nitric acid and nitrate, and the synthesis of chemicals, emissions of nitrous oxide may occur. This instrument can monitor the concentration of nitrogen pentoxide in the emitted gas in real time, ensuring that enterprises comply with environmental regulations and reduce pollutant emissions.

3. Laboratory research: In the laboratory, this instrument can be used to study the chemical properties, reaction mechanisms, and interactions with other substances of nitrogen pentoxide, providing experimental data for scientific research.
