Introduction to Analytical Ultracentrifugation

Analytical ultracentrifugation of colloids.

In this contribution the use of Analytical Ultracentrifugation (AUC) for the modern analysis of colloids is reviewed. Since AUC is a fractionation technique, distributions of the sedimentation coefficient, particle size and shape, molar mass and density can be obtained for particle sizes spanning the entire colloidal range. The Ångström resolution and the reliable statistics with which particle...

What is Analytical Ultracentrifugation?

Analytical ultracentrifugation of latexes

Analytical Ultracentrifugation (AUC) is a fractionating technique based on the synchronized optical detection of the concentration profiles of the sample under a centrifugal acceleration of up to 300,000 g. The skilled choice of solvent, rotational speed and detection optics enables a variety of complementary AUC experiments due to the controlled interplay of centrifugal force, hydrodynamic fri...

Sedimentation Velocity Analytical Ultracentrifugation

(b) Sedimentation equilibrium: an experiment performed at a lower speed so that the sedimentation and backdiffirsion forces are of comparable magnitudes and therefore give rise to an equilibrium distribution of solute concentration. Because there is no net transport at equilibrium, shape effects do not come into play and the distribution becomes an absolute function of molecular mass for a sing...
