SEPARATING PARTICLES THROUGH CENTRIFUGAL SEDIMENTATION

SEPARATING PARTICLES THROUGH CENTRIFUGAL SEDIMENTATION

A method of separating particles (P) having different sedimentation velocities in a fluid sample (30) through centrifugal sedimentation comprises enclosing the sample (30) and rotating the sample about a primary axis (12) outside the sample at a first rotational speed (Ω), and about a secondary axis...

Zusammenfassung:A method of separating particles (P) having different sedimentation velocities in a fluid sample (30) through centrifugal sedimentation comprises enclosing the sample (30) and rotating the sample about a primary axis (12) outside the sample at a first rotational speed (Ω), and about a secondary axis (22) located in the center of the sample at a second rotational speed (ξ), for subjecting the sample to a varying centrifugal field until each particle (P) has settled at a position which depends on the sedimentation velocity of the particle.
