    A cascade impactor measures the reach range of a particulate substance as it moves through an opening with the use of aerosol.Cascade impactors are strictly measurement-related devices. In addition to measuring the range of substances moved through an opening by aerosol, the impactor can also be used to determine the particle size of the distributed substance.Cascade Impactor,Automated Filter Tester QINSUN,8-stage object rotary type and rotary type MOUDI impactor 0.18-10μm M100 is precision cascade impactors with sharp cut-size and low internal-loss characteristics.

  • VARIABILITY IN CASCADE IMPACTION: SOURCES, IMPACT AND

    INTRODUCING CASCADE IMPACTION. Cascade impactors separate a sample by particle inertia, which is a function of particle size and velocity. During testing, sample laden air is drawn through the stages of the impactor at a constant volumetric flow Responses of Low Pressure Andersen Sampler for Collecting,cascade impactors (Andersen, Berner, Davis, MOUDI etc.) to measure the activity size distribution of the radon progeny in the environment (4,5,11,12). In spite of their careful use, their nonideal behavior is not adequately known (13,14).
