    CPMA Animation

    The CPMA uses opposing electrical and centrifugal fields to classify particles, with the ability to vary the electrical field and rotation speed to select different particle masses.

Animations

  • AAC Animation

    The AAC may be thought of as translating the DMA into a rotating frame, where the electrical force on the particles is replaced by a centrifugal force.
