| Abstract | The constituent particles of many ambient and workplace aerosols of health effects concerns are of fibrous and aggregate geometric shapes. The deposition sites of inhaled particles in the human respiratory system are primarily related to their aerodynamic diameters. Therefore, to assess potential exposure hazards it is necessary to have accurate kinetic classifications of airborne particulate matter. A tested theory of operation is given so centrifugal spectrometers can give direct and continuously graded measures of the aerodynamic size distributions of irregular aerosols. Aerosol centrifuge performance therefore can be customized to specific applications and be integrated into health effects studies. |
