1. A computer operated material processing apparatus comprising:

  • a centrifuge tube for containing a liquid mixture and adapted for rotation about an axis by a mechanically driven rotor so as to subject the mixture to centrifugal forces;

    a scanning device for detecting the presence of specific test particles injected into the mixture and generating scanning signals in accordance therewith;

    an injector for injecting test particles into the mixture, said test particles being detectable by said scanning device and having a sedimentation constant approximately equal to a component of the mixture that is desired to be separated;

    a computer for analyzing the scanning signals and controlling the rotation of the centrifuge tube in accordance with the scanning signals so as to localize said specific particles in a desired sedimentation layer of said tube; and

    a reaction column comprising immobilized molecules with a specific binding affinity for said test particles for removing said test particles when said mixture is passed therethrough.
