Sedimentation velocity refers to one type of experiment performed on the ultracentrifuge. In these experiments, the centrifugal field is set relatively high for the size of the molecule, and a moving concentration boundary is recorded at different times during the experiment. Analysis of the position of the boundary over time yields the sedimentation coefficient s. s depends on the weight and shape of a molecule.
The Sednterp program requires the weight of the solute and s for various shape estimates and analyses in the results section.
