Optical direct-reading particle-counting techniques have the advantage of rapid, continuous, nondestructive particle detection. However, the amount of light scattered may not be directly related to the property that one wishes to measure. By combining the advantages of optical detection techniques with the manipulation of particle motion, several instruments have been developed that detect more specific properties of aerosol particles. The aerodynamic size of particles is used to describe the behavior of particles in gravitational settling, filtration, respiratory deposition, sampling systems, and so forth.
