    摘要： The invention relates to a method for separating constituents of a liquid feed by liquid-liquid centrifugal chromatography and to a device for implementing it. Constituents (A, B) having different partition coefficients such that they are respectively carried along at unequal velocities by a light solvent (1) and a heavier solvent (L), the feed is continuously injected at an intermediate point of a separation column (col), successive cycles comprising alternately a heavy solvent injection stage and a light solvent injection stage are carried out respectively at the two ends of the column consisting of the interconnection in series of at least one set of separation cells, and the separated solvents (FA, FB) are collected during each one of said stages at the column ends opposite the solvent injection points.

    摘要： A liquid phase chromatography apparatus consists of a tubular column which is intended to receive a charge of powdery adsorbing solid material and which comprises porous plates at its ends, one of these plates being fastened there and other plate being able to move inside the column under the action of a jack and thus to compress the charge in the column. This apparatus is characterized in that charge (5) is contained in an interchangeable rigid or semi-rigid cartridge (4) with an outside diameter approximately equal to the inside diameter of column (1), the latter being cut into two equal half-cylinders (2) which are brought together after insertion of said cartridge (4) and which are kept clamped together by any suitable means (3).

    摘要： The present invention relates to a system for generating the same instantaneous pressure between two tanks filled each with a given medium, the first tank including at least one inlet channel and at least one outlet channel for the given medium, the second tank including at least one outlet channel, and means for opening and for closing said channels. The system according to the invention further includes at least one linking capillary between each tank, intended notably for transmitting instantaneously a pressure variation from the first tank towards the second tank.
