Over a decade ago, Founder and Chief Scientist at Air Quality Sciences (AQS), Dr. Marilyn Black, pioneered the environmental chamber testing technology used for product emissions testing. AQS' understanding of the technology and experience in testing a variety of products, materials, and processes has made it the industry leader in product evaluations since 1989.

AQS operates more than 30 dynamic, stainless steel chambers ranging in size from 0.05 cubic meters (m³) to 26 m³. Temperature, air moisture content, and airflow can be varied among chambers to achieve and precisely maintain required conditions. The chambers are process-controlled with thermodynamic and air distribution models that verify accuracy. AQS engineers specifically designed chambers with air purification systems and construction materials that achieve non-detectable background levels for contaminants so that very sensitive analyses may be conducted. Test protocols follow ASTM Small and Full-scale Chamber Standards, D5116-97 and D6670.

AQS' technology offers many benefits to Product Evaluation customers:

• Complete VOC analysis - Other laboratories test exclusively for the presence of a target list of frequently used volatile organic compounds (VOCs). AQS' unique technology identifies and measures all VOCs that are present in the air, painting a complete picture of what is there.
• 13 years' experience - AQS has tested the emissions of more products than any other laboratory in the world. Having tested over 30,000 products, AQS has historical data and superior knowledge that only experience can bring.
• Parts per billion level testing - AQS' environmental chamber technology allows accurate, precise, and sensitive detection of VOCs, formaldehyde, particles, and other contaminants of concern, including microorganisms, down to the parts per billion level.
