Abstract: | The recent development in this laboratory of an automated data capture system, for refractometric optics on the analytical
ultracentrifuge has removed the requirement for tedious and time consuming manual acquisition which had led to a decline in
the use of schlieren optics. At the same time this system has increased the amount of data easily available from such an optical
system with maintained or increased precision. From the advent of such a system has arisen the need for a package to facilitate
the analysis of these data and to extend the range of analytical methods used. Using the improved data sets now available
has also enabled us to successfully use methods which have lapsed in popularity over the last two decades. We have also been
able to successfully apply radial derivative methods (Bridgman 1942) which have not routinely been applied to the analysis
of sedimentation velocity experiments using schlieren optics. In this paper we describe the methods we have so far used to
analyse data and present results for previously well defined molecules to demonstrate that the results obtained are reliable.
