January 27, 2011

ANTIOCH, Calif., Jan. 27, 2011 /PRNewswire/ — The Avogadro Group, an emission testing company headquartered in the San Francisco Bay Area was one of a select number of companies nationwide chosen to work on a U.S. Environmental Protection Agency (EPA) project to perform side-by-side analysis comparison of old and new PM2.5 emission testing methods.

“Being one of the companies chosen to collect this important data highlights our role as an industry leader in particulate matter (PM) emission testing and measurement,” says Craig Thiry, business development director at The Avogadro Group. “We have spent years perfecting analytical procedures for measuring PM.”

By making several side-by-side comparisons of the old PM2.5 sampling method with the newly revised method, The Avogadro Group delivered results showing that the revisions to Method 202 changed this method from one that could produce a wide range of results and that suffered from interferences to a standardized method producing more consistent results with much less interference from SO2 or other stack gases.

The EPA has promulgated the new sampling method, which now gives every regulatory agency the opportunity to use the new method for more consistent, more accurate test results for PM2.5 emissions from stacks and exhausts. The Avogadro Group is pleased to have been a team member in this research so important to new strategies for improving air quality.


The Avogadro Group, LLC is a source testing and consulting firm that focuses on combustion and process-generated air pollution emissions, emissions measurement, emissions control devices, CEM systems and regulatory affairs.

The company has offices in the San Francisco Bay Area city of Antioch, California, Medford and Portland, Oregon and a recently opened office in Phoenix, Arizona and services clients throughout the United States and internationally.
