Passive sampling of airborne particles with the aid of natural air flow

An apparatus for passive sampling of airborne particles such as those found in an aerosol is disclosed. The passive sampler is designed to take advantage of natural air flow to collect airborne particles, such as those contained in an aerosol, for subsequent analysis. The passive sampler increases the sampling efficiency for diffusion and electrostatic collection of particles by using natural airflow or movement to bring particles closer to the deposition surface. Alternately charged electret filters further increase the sampling efficiency.
