A new apparatus for the chromatographic separation of liquid mixtures is investigated. The apparatus contains a number of vertical columns connected in a serpentine shape and consisting of cells placed on top of each other. The cells in the columns are separated by perforated septa. A special dosing unit is used to provide a discrete (cyclic) mobile-phase feed [flow?] into the apparatus and a pulsed cyclic mode of phase contact in column cells. Studies on a single column and on an apparatus consisting of four columns have been performed to assess the efficiency of the pulsed cyclic device. The results of experimental investigations have confirmed the potential of the newly developed topic in the area of liquid mixture separation processes.
