High-performance zone electrophoresis
TL;DR: In this article, an experimental approach to high-performance zone electrophoresis is given, where dispersion can be well controlled by the use of narrow-bore tubes made of chemically and electrically inert materials.
Journal ArticleDOI
Free zone electrophoresis
TL;DR: The free zone electrophoresis method described in this monograph can be used for the fractionation of small molecules, large molecules, and particles, and its versatility is illustrated in runs with inorganic ions, organic ions, nucleic acid bases, nucleosides, nucleotides, proteins,ucleic acids, subcellular particles, viruses, and erythrocytes.

Concentration distributions in free zone electrophoresis
TL;DR: In this article, the effect of electrophoretic migration on the concentration distributions in free zone electrophoresis is evaluated using a non-diffusional model, and it is shown that sample constituents that have a mobility higher than that of the carrier constituent migrate with a concentration distribution that is diffuse at the front and sharp at the rear of the zone.
