• Description:
  In this paper, we describe the design, development and characterization of a high-volume sequential cyclone system for the collection of size-segregated PM in dry bulk form from the ambient environment in sufficient quantity for physical, chemical and toxicological characterization. The first stage of the system consists of a commercially available high volume PM10 inlet. The second stage cyclone was designed by us to collect inhalable coarse particles (<10 microm and >2.5 microm). When tested individually with a challenge aerosol, a D50 cut-size of this stage was found to be 2.3 microm at a flow rate of 1 m3 min-1. The third stage, a commercially available cyclone designed for surface dust sampling, had a D50 cut-size of 0.3 microm when tested at the same flow rate. The purpose of the third stage is to collect the fine particle portion of PM2.5 or accumulation mode (PM <2.5 microm and >0.1 microm). Thus, the sequential cyclone system will collect bulk samples of both the inhalable coarse particles and the fine particle portion of PM2.5. The operation and maintenance of the new system are straightforward and allow for reliable collection of dry bulk ambient PM at relatively low cost. [Description provided by NIOSH]
