Air Emissions Testing

Identify the type and amount of contaminants in air emissions from stacks and ducts with air emissions testing from SGS.

Air emitted from stacks and ducts must be tested for pollutants, particularly matter, gases and fumes, and vapors. Quantifying the type and amount of pollutants in the air emissions will allow:

  • Compliance evaluation with existing or proposed emission regulations
  • Quantification of financial losses from product escapes
  • Collection of engineering data for control equipment design
  • Assessment of the efficiency of installed control equipment
  • Collection of emission data for modeling
  • Calibration of continuous monitors
