Homogeneous gels for capillary electrochromatography

Summary, in English

Homogeneous gels represent a new type of (electro)chromatographic media possessing unique separation properties unmatched with any other chromatographic beds. It is important to emphasize that they principally differ from continuous beds, polymer rods (better known as monoliths), which are particulate separation media with pores permitting hydrodynamic flow through the columns. Monoliths, thus, are more similar to beds conventionally packed with beads, although the particles building up monolithic columns are usually smaller in size (few submicometers) and covalently linked together. Consequently, homogeneous gels deserve better the term “monoliths” having a non-particulate structure formed by crosslinked free polymer chains (according to a dictionary a monolith is a non-modularized column). The goals of this minireview are to clarify the position of homogeneous gels among the separation media (including polymer solutions), to explain and to exemplify their outstanding (electro)chromatographic properties. This review gives hopefully a complete list of references to homogeneous gels developed for capillary electrochromatography.
