Method for loading a capillary channel with a packing material to form a capillary column which includes placing a first frit on a capillary channel, forcing a slurry of a solid packing material in a liquid (70) through said first channel so that the liquid (70), but not the solid packing material, passes through the frit and out of the capillary channel, to form a first bed (21) of packing material within said first capillary channel and adjacent to the frit; thereby forming a pre-pack column (20), then removing the frit and joining the pre-pack column (20) to an empty second capillary channel (30) and attaching a second frit (9) to the end of said second channel (30), then forcing a liquid (70) into the end of pre-pack column (20), so that the liquid (70) passes through the pre-pack column (20), mobilizing the packing therein and carrying it into the second capillary channel (30).
