The ultracentrifugation (UC) method achieves separation of free and protein bound drugs by centrifugation of the sample in a tube without a membrane. It makes use of the fact that sedimentation of solutes depends upon their molecular weight. The first time Steinberg and Schachmann (1966) demonstrated theoretically and practically the potential of the method.

The type of mutarotation kinetics found experimentally is strongly dependent on the solvent. Forward mutarotation in acetic acid yields a plot of log d[a /dt versus log ([a]( — [ ] ) which is linear over 97% of the reaction with a slope of 1.33. On the other hand the rate is virtually invariant over two-thirds of the reaction in a solvent of 30% water-70 % acetic acid. Reverse mutarotation in acetic acid-n-propanol appears to follow first-order kinetics over 90% of the transformation. From these experiments and the fact that the enthalpies of form I and form II are essentially identical (Steinberg et al., 1960a) it seems likely that solvation is decisive not only in determining the kinetic pathway of mutarotation but also the structural pattern which is stabilized in a given solution.

Trivalent and some bivalent cations can precipitate HSs under the right pH conditions from dilute solutions. Precipitation or aggregation of organics with cations is facilitated at low temperatures, most likely due to the copredpitation effect with carbonates (Steinberg and Muenster (1985)). However carbonates ate more soluble at low temperatures.
