Abstract
A method of fabricating an elution chromatography separating column from an elongated capillary tube, such column having a layer comprising a plurality of disunited particles of porous solid material disposed on an inner surface of the tube. The method comprises the steps of: preparing a suspension comprising a dispersive liquid and particles of the solid material; filling an elongated capillary tube with prepared suspension; and flowing an inert gas through the tube to dry the tube thereby leaving a layer comprising a plurality of disunited particles of the solid material attached to the inner surface of the tube.
