Airborne particle measurements: 100 LPM vs. 1 CFM particle counters in a semiconductor cleanroom environment

Abstract Many current standards define airborne particle monitoring in units of particles-per-cubic-meter (particles/m3). Often, these standards require sampling an entire cubic meter (1 m3) to provide an accurate measurement of airborne particulate levels. Using a conventional aerosol particle counter that samples 1-cubic-foot per minute (1 CFM) requires more than 35 minutes to sample 1 m3. ...

Air Pollution in Subway Systems May be Much Worse than we realized

As anyone who has ridden the subway knows, the air down there is unpleasant. New research done in Canada shows that air pollution levels in Toronto’s subway system are ten times greater than ...

ERM-CZ110: a new Certified Reference Material for analysis of airborne particulate matter

Airborne particulate matter is a major problem in many densely populated areas of the world. This pollutant is a mixture of particles of different size and composition, originating from different sources. The finest fraction of these particles, the ...

Particulate Monitor System

The Spirant BAM automatically measures and records airborne particulate concentrations using the beta ray attenuation method. It is designated by the U.S. EPA as Federal Equivalent Method for PM10 and PM2.5 monitoring.
