  • Patent number: 10675558
    Abstract: A dispersed mobile-phase countercurrent chromatography system is described in which solutes are carried by a stream of dispersed mobile phase solvent through a column, or array of serially-connected columns, of stationary phase solvent with which the mobile phase solvent is immiscible. Solutes carried along by the stream of dispersed mobile-phase solvent will be equilibrated between the mobile-phase solvent and the stationary-phase solvent. Because the mobile-phase is dispersed into mini-droplets much smaller in diameter than the column of stationary phase, the enhanced surface/volume ratio of the droplets expedites countercurrent equilibration of different solutes between the mobile-phase solvent and the stationary-phase solvent in accordance with the distribution-coefficients of the solutes between the two solvents.
