ABSTRACT:
To form a gel bed in a cylindrical column for liquid chromatography, a gel bed section is provided between upper and lower liquid-tight partition members, positioned apart from each other at upper and lower positions in the column. Liquid is continuously percolated downward through the gel bed section to form a gel bed in the gel bed section and a liquid pressure is applied onto the upper partition to move the partition member downward following a downward movement of the upper surface of the gel bed.
