DOUBLE FLOW CHROMATOGRAPHY SYSTEM

摘要

The disclosed invention relates to a new liquid chromatographic method, wherein the flow direction of sample is directed alternately in an essentially horizontal direction and in an essentially vertical direction through a separating matrix having a dimensional ratio between the column width and column height of at least 1:0.5, preferably at least 1:0.2, more preferably at least 1:0.1 , even more preferably at least 1:0.04. The invention further relate to an apparatus and a column design for controlling the flow direction of a liquid sample through a separating matrix in either an essentially horizontal or in an essentially vertical direction.
