Method and apparatus for the manipulation of particles sedimenting

A method for the manipulation of particles (1, 2) which are suspended in a carrier liquid (3), comprising the steps of receiving the carrier liquid (3) with the particles (1, 2) in a liquid lift means (10) with at least one siphon opening ( 11) generating electrical and / or magnetic separating fields in the liquid siphoning device (10), sedimentation of the particles (1, 2) in the liquid, each particle has a sedimentation rate, which in this particle (of the action of the separating fields 1, 2 ) depends, and the particles (1, 2) in dependence on their sedimentation several particle fractions (5, 6 form), and separate the particle fractions (5, 6) from the liquid siphoning device (10). There is also described a manipulation apparatus (100) for manipulation of suspended particles (1, 2).
