Column for capillary chromatographic separations and method of manufacturing same

摘要

A column for capillary chromatographic separations, for example high performance liquid chromatography, capillary electrochromatography, or supercritical chromatography, comprises a column bed (2) of packing material arranged in the inner bore of a capillary (1), wherein said bed of packing material (2) is completely immobilized by a thermal treatment. The thermal treatment preferably comprises moving a heating wire (3) along the column while applying pressure to the column using a high pressure pump (6). <IMAGE>
