NO2 (Nitrogen Dioxide) Measurements

Nitrogen dioxide is a brown and poisonous chemical compound that plays red. The smell of this gas, which has a very pungent odor, is similar to some chlorine gas. Severe coughing if inhaled. 200 is decomposed at temperatures and produces nitrogen oxide (nitrogen monoxide) and oxygen gases. Nitrogen dioxide is a very good water-soluble compound.

Nitrogen dioxide (NO2) is produced by the combustion of fossil fuels such as gas, coal and oil. Therefore, especially in the waste gases of motor vehicles and the combustion of the gas and coal used for heating, a large amount of azide dioxide is released into the atmosphere. In addition, a small amount of nitrogen dioxide is produced in the paper industry at some stages of paper production. Nitrogen monoxide (nitrogen oxide) and nitrogen dioxide are very effective compounds in terms of air pollution. These compounds have toxic effects on human health and corrosive effects on materials. Therefore, nitrogen oxide and nitrogen dioxide measurements carried out by authorized laboratories are of great importance.

It is not easy to detect nitrogen dioxide at low concentrations. However, this gas is highly toxic and if inhaled symptoms such as dizziness and headache occur in humans.

Our company performs nitrogen dioxide (NO2) measurements within the scope of gas measurements. In these studies relevant legal regulations, standards and test methods published by local and foreign organizations. These standards are based on a few standards:

  • TS EN 16339 Ambient air quality - Method of determination of nitrogen dioxide concentration by chemical diffusive sampling
  • TS EN 14211 Ambient air quality - Standard method for the determination of nitrogen dioxide and nitrogen monoxide concentrations by chemical chemiluminescence
  • TS ISO 8761 Workplace air - Determination of nitrogen dioxide mass concentration - Detector tubes method used for short-term sampling with direct indication
  • TS ISO 6768 Ambient air - Determination of the mass concentration of nitrogen dioxide - Improved Griess-Saltzman method
  • TS EN ISO 16000-15 Indoor Air - Part 15: Sampling Strategy for Nitrogen Dioxide

In the meantime, our organization, ÖSAS Accreditation Agency, Accredited according to TS EN ISO / IEC 17025 standard.
