in this technique, density gradient column encompasses the whole range of densities of the same particle. so at the end of centrifugation each component of the solution will sediment to the position which the density gradient is equal to its own density.

Zonal Density-Gradient Centrifugation Most textbook illustrations of the Meselson – Stahl experiment show it being conducted in a conventional swinging-bucket type centrifuge rotor. Such rotors are described as preparative, because the ordinary purpose is to prepare cell fractions based on differences in density, typically by sedimenting out a heavier fraction from a lighter supernatant fraction.
