ABSTRACT:
A cyclone type personal aerosol sampler has a two-stage operation with a standard cyclone sampler providing a cutoff of particles in the range of 10 microns to a secondary cyclone sampler. The secondary cyclone sampler has the ability to inertially separate out particles below about 0.8 microns from larger particles. The secondary sampler has a readily removable cup for collecting the larger particles, and an easily replaceable filter for collecting the smaller particles for analysis.
