Ambient Air Quality Monitoring System Principle

AAQMS (ambient air quality monitoring System) for continuous monitoring of pollutant gases like NO2, SO2, O3, CO and suspended particulate matter like PM10 and PM2.5 Ambient Air Quality Monitoring Parameters As per norms below mentioned parameters are mandatory for air quality. CO : Carbon Monoxide SO2: Sulphur Dioxide NO2 : Nitrogen Dioxide O3: Ozone PM10: Particulate Matter The following provides information about the basic principles used for measurement. Sulfur dioxide (SO2) : Sulfur dioxide (SO2) is measured continuously by instruments using the fundamental principle of fluorescence. Fluorescent analyzers irradiate an ambient air sample with ultraviolet light at 213.8 nm. Sulfur
