During the last few years Svedberg has completed an extremely ingenious invention, the so-called ultracentrifuge, which enables highly interesting investigations to be made also on such molecular-disperse systems.    From Wordnik.com.  [Nobel Prize in Chemistry 1926 - Presentation Speech] Reference

His greatest achievement was, however, the construction of the ultracentrifuge, with which he studied not only the particle size distribution in gold sols but also determined the molecular weight of proteins, for example, hemoglobin.    From Wordnik.com.  [The Nobel Prize in Chemistry: The Development of Modern Chemistry] Reference

Svedberg's investigations with the ultracentrifuge and Tiselius's electrophoresis studies (see Section 3.10) were instrumental in establishing that protein molecules have a unique size and structure, and this was a prerequisite for Sanger's determination of their amino-acid sequence and the crystallographic work of.    From Wordnik.com.  [The Nobel Prize in Chemistry: The Development of Modern Chemistry] Reference
