Ambient Air laboratories may also do the following tests:

Particulate matter (PM) measurement: Determines the concentration of particulate matter (PM2.5 and PM10) in the air Testing
using methods such as gravimetric analysis and light scattering Testing
Gas analyzers: Measure concentrations of gases like ozone (O3) Testing
nitrogen dioxide (NO2) Testing
sulfur dioxide (SO2) Testing
and carbon monoxide (CO) through techniques including chemiluminescence Testing
UV fluorescence Testing
and infrared absorption Testing
