A system for the sampling of inhalable airborne particles.
This paper describes an instrument developed for the semi-continuous measurement of aerosol mass and its classification into three classes. These classes have been chosen to evaluate the health hazards caused by inhalable particles. The instrument takes samples through three probes, each providing different cut-off points ( approximately 15 microm, approximately 4 microm, approximately 2 microm) and collects airborne particles on circular membrane filters. The increase in weight is measured by the beta-ray attenuation method.
