Sedimentation and Diffusion and Their Equilibrium

Even if you had completed your third year … in the University, and were perfect in the theory of the subject, you would still find that there was need of many years of experience, before you could move in a fashionable crowd without jostling against your betters.

From Abbott’s Flatland

2.1  INTRODUCTION

2.1a  Sedimentation and Diffusion: Why Are They Important?

Sedimentation and diffusion affect many colloidal phenomena. Sedimentation occurs under the influence of gravity and, considerably faster, in a centrifuge. Many analytical and preparative techniques in colloid science (particularly in biophysics and biochemistry) take advantage of centrifugal force for physical characterization or purification ...
