tiselius apparatus การใช้

With more assistance from the Rockefeller Foundation, the expensive Tiselius apparatus was built at a number of major centers of chemical research.
By the late 1940s, new electrophoresis methods were beginning to address some of the shortcomings of the moving boundary electrophoresis of the Tiselius apparatus, which was not capable of completely separating electrophoretically similar compounds.
In order to measure this difference precisely, Pauling assigned graduate student John Singer to work with Itano and another medical researcher, Ibert C . Wells, on using a " Tiselius Apparatus " to perform free-boundary electrophoresis, before leaving in early 1948 for a guest lectureship in England.
