Ambient Gaseous sampling Systems

Ambient Gaseous sampling Systems

It is widely recognized that Particulate Matter pollution has the greatest effect on human health. However, extensive studies have shown that there exist a number of gaseous pollutants which when present in the ambient air beyond specified limits can also seriously endanger the health of humans.

A number of these gaseous pollutants are recognized as primary pollutants. These include :

• Sulphur Oxides (SOx)
• Nitrogen oxides (NOx)
• Carbon monoxide (CO)
• Ammonia (NH3)
• Volatile organic compounds (VOC)

A number of secondary pollutants may also pollute ambient air. Some of these include :

• Ground level ozone (O3)
• Peroxyacetyl nitrate (PAN)

Gaseous sampling involves the entrapment of gaseous pollutants in specific entrapment media. The media is generally of two types :

• Wet chemical solution
• Solid Adsorption media

We manufacture a variety of gaseous sampling systems for sampling of various gaseous pollutants based the following parameters :

• 1. Entrapment media
• 2. Number of simultaneous gaseous pollutants to sample
• 3. Stand alone sampling or in combination with particulates
• 4. Type of cooling arrangement
