Stationary Source Emissions - Determination of NO, NO2 and NOx Emissions

Stationary Source Emissions-Determination of Nitrogen Monoxide (NO), Nitrogen Dioxide (NO2) and Nitrogen Oxide (NOx) Emissions

What are NO, NO₂ and NOx?

• NO (oxides of nitrogen): Nitrite oxides, often called nitrogen oxides. They are usually formed when nitrogen and oxygen gases react under high temperature. NO is a reactive and hazardous gas and is often formed in gas combustion processes.
• NO₂ (dioxide nitrogen): A compound that is less stable and more dangerous in the atmosphere. It is formed from NO with the addition of oxygen and has acidic properties. It is an irritant gas for the respiratory tract.
• NO_x ( total oxides of nitrogen): Refers to the sum of NO and NO₂. NOx emissions usually originate from combustion processes and industrial processes. They contribute to air pollution and can cause acid rain.

_NOx emissions, called nitrogen oxides, usually in the forms of nitrogen monoxide (NO), nitrogen dioxide (NO₂) or diazote monoxide (N₂O), are colorless and odorless gases that are toxic to humans. NOx emissions are harmful and polluting parameters for the living population and environmental health.

For the protection of the environment and the continuation of natural life, various pollutants such as NOx  emissions should be monitored and regularly controlled within the scope of relevant legal regulations and standards. It is important to determine the concentrations of nitrogen monoxide (NO), nitrogen dioxide (NO₂) and NOx as a total in controlled and uncontrolled emissions from combustion sources such as boilers, heaters, engines and turbines.

Determination of Nitrogen monoxide (NO), Nitrogen dioxide (NO₂) and Nitrous oxide NOx Emissions from Stationary Source Emissions

These processes are carried out by the “Electrochemical Cell Method”. In the measurement process carried out with the EPA CTM 022 Method; a gas sample is continuously extracted from the source and a portion of the sample is transmitted to an instrumental electrochemical analyzer to determine NO, NO₂ and NOx concentrations. Reliable data can be obtained if the instrument used is suitable, calibrated and the emission measurement procedures are carried out by authorized and knowledgeable persons.

Nanolab Laboratories Group continues to provide services within the scope of Stationary Source Emissions. We also provide services in Emission - Imission Measurements.
