A Graphical Method for Determining the Ideality of a Sedimenting Boundary

Analytical ultracentrifugation can provide useful thermodynamic and hydrodynamic information for a wide variety of chemical systems. It is apparent that through the use of modern electronics and computers, analytical ultracentrifugation is undergoing a renaissance. A modernization of ultracentrifugation is underway. The automation of acquisition, reduction and analysis of data has been quite successful. However, what has been more difficult to automate is the art of determining how much information is accessible from an experiment. This is a problem that becomes apparent to anyone starting a project that involves analytical sedimentation.
