Key Points

Investigate anomalous boundary behavior occurring during the analytical ultracentrifugal sedimentation of multicomponent mixtures.
Analyzed the sedimentation velocity profiles of macromolecular mixtures in an analytical ultracentrifuge.
Tracked boundary formation, displacement rates, and concentration gradients across mixed solute systems.
Identified marked deviations in boundary patterns when solutes sediment together compared to when they sediment individually.
Observed that inter-particle hydrodynamic and Johnston-Ogston-type effects alter the apparent concentration and migration rates of mixture components.
