A continuous chromatographic separation is effected by a column packed with finely divided chromatographic particles, the nature of which depends on the materials to be separated. In the case of liquid systems, the cylinder containing chromatographic packing is substantially horizontal and is spun to develop substantial centrifugal force. Preferably, the cylinder is of suitable porous material, such as a ceramic of the type used for filtration. The liquid, having dissolved or suspended therein the constituents to be separated, is introduced at one end under substantial pressure, for example by a pump, which, preferably, rotates with the cylinder. The cylinder is supported along its length by non-corrosive, such as stainless steel, rings. The rings are held together by through-bolts and, if necessary, spacers. In the case of a porous ceramic cylinder, the pores are small, and there are stationary troughs at the peripheries of each pair of rings which receive liquid coming out. For horizontal cylinders there are drain holes in the lower trough which permit the liquid to go into collectors at predetermined points along the cylinder. The sample, which is introduced under some pressure, moves along the chromatographic packing, and separation of various constituents is effected chromatographically.
