Abstract
Disclosed is an assembly for continuous annular chromatography provided with a relative movement between one partial bed in the form of a cylinder jacket, at least one feeding position for liquid feeding material and at least one collection position for every emerging fraction of the feeding material out of the partial bed.
Claims10
An apparatus for continuous annular chromatography of liquid feed material, comprising:
- at least one feed point for liquid feed material;
- an upright cylindrical jacket rotatable about its axis and filled with a particle bed;
- a base plate which is connected to the cylindrical jacket;
- and
- a collecting ring adjacent the base plate, wherein the cylindrical jacket comprising said particle bed rotates relative to said at least one feed point and to said collecting ring and the base plate rests on the collecting ring and slides while providing a seal, wherein the base plate further contains liquid channels widening towards the particle bed and connecting the particle bed with the collecting ring, and wherein the collecting ring comprises chambers separated by radial walls, each chamber comprising a means for pressure equilibration.
