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