ABSTRACT:
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).
