ABSTRACT:
A method of and a device for chromatographic separation of fluid mixtures into fractions by means of circulation of a continuously fed mixture in a system of several separating columns adapted for simultaneous passing of two independent fluid streams through separate series-connected parts of column system with a synchronized replacement of the inlet and outlet points of the fluid streams and inlet point of the mixture along the columns, comprising in accordance with the present invention, preliminary separation of the mixture by means of circulation in a system of at least three columns into two fractions being discharged from said system by two separate fluid streams; with subsequent passing of one or both streams containing the preliminarily separated fraction in the form of a mixture of substances through one or two additional separating columns respectively, wherein the fraction is separated into narrower fractions or individual components.
