Abstract
Both a column having high-pressure resistance and capable of performing high-speed separation and analysis even with a small flow rate and a liquid chromatograph apparatus using the column are provided. A separation column according to the present invention has a monolithic rod being arranged in the center, being made of a porous material, and having a circular cross section, a filler layer arranged such that it encircles a circumferential surface of the monolithic rod, and a cylindrical support medium arranged outside the filler layer. The filler layer is formed by filling a tube-like gap between the monolithic rod and the support medium with particles or beads.
