Sedimentation equilibrium

Sedimentation equilibrium is a technique used in biochemistry to separate a sample containing several components based on their various densities.

The sample containing the mixed components is layered on top of a density gradient of a substance such as sucrose or cesium chloride and centrifuged until the equilibrium is reached. The discrete layers can then be easily separated.
