Ambient Air Quality

Australians consistently rank air pollution as a major environmental concern. The state of our air is an important factor in the quality of life in Australian cities as it affects the health of the community and environmental effects that directly influences the sustainability of our lifestyles. Sources of air toxics include motor vehicles, solid fuel combustion, industrial emissions and material such as paints and adhesives in new buildings.

Lear Siegler manufacture and source from a range of world class companies a wide range of instrumentation for your individual air quality monitoring needs in particulate matter or gaseous pollution. Whether you require collection of a sample using a reference instrument or require real time on-line measurement we have the instrument for you.

The methods to choose from to measure particulate matter in ambient air are either by using a reference instrument or real time on-line measurement. A reference instrument will take a defined sample of particulate matter in the ambient air and that sample will have to be taken to a lab for analysis.

The other method is real time on-line measurement. Real time on-line measurement is a continuous measurement which is dated and time stamped and can be done by any of the following methods.

• Beta Gauge (Radioactive Absorption)
• Tapered Element Oscillating Microbalance
• Light Scattering
• Combination of Light Scattering and Beta Gauge

The method that you choose will depend on your application and size of particulate matter you are required to measure from TSP, PM 10, PM 2.5 individually or combined.

When you are measuring gases in the ambient air you have various technologies for different gases measurement.

• Non-dispersive Infrared (NDIR),
• Fourier (FTIR),
• Chemiluminescent,
• Pulsed florescent,
• UV absorption
• Flame Ionization Detector
• Paramagnetic
• Electrochemical

Whatever the gas Lear Siegler can assist you to choose the best type of instrument for your measurement needs.
