Second generation dichotomous sampler for large-scale monitoring of airborne particulate matter

Conference ·
OSTI ID:6426688

The differences which exist between fine (< 2.5 ..mu..m) and coarse (> 2.5 ..mu..m) airborne particles with respect to their origin, chemical properties, and environmental impact, call for their separate collection and analysis. An automated dichotomous sampler (ADS), equipped with a high efficiency single-stage virtual impactor and a microprocessor-based controller to self-correct fault conditions including filter overload, has been developed as a model for commercial production.
