method based on the fact that at the meniscus and at the bottom of the centrifuge
cell there is never a flux of the solute across a plane perpendicular to the radial
direction and the equations characterizing the sedimentation equilibrium
always apply there, even though the system as a whole may be far from equilibrium.
The use of the term 'approach to sedimentation equilibrium
' for Archibald's method is discouraged, since it has a more general meaning.
