Rapid Separation op Cells at Unit Gravity

Preparative Biochemistry, 1977
An apparatus is described for the rapid separation of cells at unit gravity. The apparatus is filled with a discontinuous density gradient, followed by the sample and then an overlay. The sedimentation chamber is turned from a vertical to a horizontal position before sedimentation takes place in order, (a) to form a continuous gradient out of the ...

Gravity separation by entropic transport

EPL (Europhysics Letters), 2015
We propose a new method of gravity separation by entropic transport. Through tuning the geometry parameters or the amplitude of the external force, the average current of particles can be modified in confined nano-structures, thus leading to an effective particle separation according to their weights.

Approximation Functions of Separation Curves for Gravity Separators

IFAC Proceedings Volumes, 2006
Abstract The series of real-valued functions has been presented in the paper. It has been stated that this series of functions can be considered as the series of probability density functions. All probability density functions which constitute defined series of functions have the same mean value and the same variance.
