Cascade Impactor an overview ScienceDirect Topics. Cascade impactor is mostly used for particles in the range of about 0.1–100 µm. In principle, during the operation of the cascade impactor, the particles in the sample move and classify themselves according to the size of particles. Then, particles are collected in series on collecting plates.
