A LITERATURE SURVEY OF METHODS FOR FRACTIONATED SUSPENDED PARTICULATE MATTER MEASUREMENT

Abstract

Literature review suggests the US-type dichotomous sampler (virtual impactor) as the best commercially available device for suspended particle fractionation/gravimetric analysis at this time. The size selective high volume sampler lacks a reliable fractionator, but collects optimum particle mass for gravimetry. Field comparison trial of candidate samplers is recommended.
