ABSTRACT:
The invented column for liquid chromatography consists of a glass tube, which is inserted into a metallic tube. The metallic tube is provided with recesses in its inner wall at both ends, which accommodate conic tightening rings from metal together with conic circumferential packings from plastics, advantageously from poly(tetrafluoroethylene). The column further consists of front packings from plastics, advantageously from poly(tetrafluoroethylene, which have porous disks or filter gauzes pressed into their recesses. Both types of packing are tightened with metallic terminal elements screwed on the metallic tube, which are provided with expansion slots at sides adjacent to the front packings. The metallic tube may have openings for a visual inspection of column packing.
