ABSTRACT:
A method of filling a capillary with a substantially void-free gel by forming the gel outside of the capillary and then extruding the gel into the capillary. The initial gel can be formed as a rod of gel much larger in diameter than the capillary into which it is to be extruded. This rod of gel is rinsed to remove polymerization contaminants and then dried to form a dried gel preform. The gel can be resolvated with a compatible solvent and then extruded into one or more capillaries.
