title: A Comparison of Filter Types in the Collection and Gravimetric Determination of Airborne Particulate Matter Less than 2.5 Microns (PM25).
abstract: Five identical, collocated, low-volume samplers were operated to collect airborne particulate matter less than 2.5 microns (PM25). Five commercially available filter types were installed in the samplers to compare the gravimetric determination of PM2.5concentrations in the atmosphere. The filters were rotated through the five samplers for two study periods-one in summer and one in winter. The study was performed in Sheridan, WY, in close proximity to a gravimetric laboratory to minimize the introduction of errors associated with sample handling. Rigorous quality assurance procedures were employed throughout the study.Four of the five filter types provided comparable gravimetric determinations of airborne PM2.5.
