Why denser particles settles at d bottom in centifugation technique?
Answers
Explanation:
By applying a larger effective gravitational force to the mixture, like a centrifuge does, the separation of the particles is accelerated. This is ideal in industrial and lab settings because particles that would naturally separate over a long period of time can be separated in much less time.
The particle concentration increases with the increase in the depth of the dispersion system. These differences will lead the diffusion of particles from the bottom to the surface. The diffusion caused is in the direction opposite to the settling, therefore, becomes the resistance to the settling. When the diffusion velocity equals the settling velocity, the dispersion system reaches the equilibrium state, which is referred to as sedimentation
