    Development of inertial impactors for measurement of aerodynamic diameters of man-made organic fibers

    COLLAZO H.; CROW W.A.; GARDNER L.; PHILLIPS B.L.; MARPLE V.A.
    Eastman Chemical Company, Kingsport, TN, USA
    It is widely accepted that the aerodynamic diameter of a particle is one of the main factors which determine particle deposition into the human respiratory system. The determination of aerodynamic diameter of spheres or near spherical objects is routinely ...

    Application of inertial impactors for the measurement of aerodynamic diameters of cellulose acetate fibers

    COLLAZO H.; CROW W.A.; GARDNER L.; PHILLIPS B.L.; MARPLE V.A.; UTELL M.J.
    Eastman Chemical Company, Kingsport, TN, USA
    The aerodynamic diameters of particles and fibers greatly influence their site of deposition and toxicity in the respiratory tract. To characterize cellulose acetate fibers released from the filter end of cigarettes, we designed a multistage impactor to ...
