Foam Chromatography: Recent Developments

Foam chromatography is a continuous Chromatographic separation technique in which liquid foam, moving in plug-flow upwards in a vertical column, is used as a sorbent. The eluent is a solution (below the CMC) of the foam-stabilizing surfactant. In this paper we present the results of a study of the parameters that control the operation of a foam chromatography system. The capacity of the system for complete separation of binary mixtures is determined by foam velocity, elution rate, the distance between the injection point of solutes and the bottom of the foam-column (“damper zone”)‚ and to a lesser extent by the distance between the injection points of eluent and solutes (“elution zone”). The interpretation of these results gives a better understanding of the mechanism of separation, and may lead to an efficient design of foam chromatography systems.
