Hydrodynamic Chromatography

Hydrodynamic chromatography (HC), as a new method for the separation of the particles of submic-rometre sizes, was described by Small in 1974. HC is not a variant of SEC although some processes can participate in the separation mechanisms of both methods. It is not a subtechnique of FFF although the hydrodynamic phenomena can actively participate in the separation mechanism of FFF whose fundamental characteristic is the selective migration of the separated species due to an effective field. Formally, HC could be considered as a limiting case of FFF when the intensity of an effective external field is zero.
