Abstract
Official abstract text for this publication.
The present application relates to a liquid distributor and collector for columns for liquid chromatography with preferably round cross section, which is particularly suitable for columns with large diameter in relation to the packing height.
First claim
Opening claim text (preview).
The invention claimed is: 1. A round-shaped liquid distributor and liquid collector for chromatography columns, comprising at least one liquid inlet and outlet opening and connecting flow channels between the at least one inlet and outlet opening to equidistantly arranged openings to a column packing, wherein some of the connecting flow channels are of symmetrical T-distributor shape, the rest of asymmetrical T-shapes, and the same time is required for flow from the inlet to the outlet of the liquid distributor or collector through the different connecting flow channels, and the same length and the same cross-sectional area, and the connecting flow channels of asymmetrical T-distributor shape have a different length and a different cross-sectional area than the connecting flow channels of symmetrical T-distributor shape, and the cross section of the liquid distributor or collector is round. 2. The round-shaped liquid distributor and collector of claim 1 , wherein one opening to the column packing is provided for each 50-5000 square millimeters of cross-sectional area of the column packing. 3. The round-shaped liquid distributor and collector as claimed in claim 1 , wherein the connecting flow channels are arranged in one plane. 4. A chromatography column comprising the round-shaped liquid distributor and collector of claim 1 . 5. A method for analytical and preparative chromatography which comprises conducting said analytical or preparative chromatography in a chromatographic column having a round-shaped liquid distributor and collector of claim 1 .
