MSH: Separation of particles according to density by employing a gradient of varying densities. At equilibrium each particle settles in the gradient at a point equal to its density. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed),CSP: separation of particles in an ultracentrifuge according to density by employing a gradient of varying densities; at equilibrium each particle settles in the gradient at a point equal to its density.,NCI: A method of separating macromolecules by either their differential rate of sedimentation in a centrifugal gradient or their differential buoyancy in a density gradient.
