Filed: 1993-10-22
Abstract: PURPOSE:To simplify separation mode, guarantee reproducibility and accelerate a chromatographic separation process by using a porous columnar body having a narrow hole penetrating from the top thereof to the bottom as the column. CONSTITUTION:A fine hole having a circular or nearly circular cross section perpendicular to the axial direction is formed from the top of a porous columnar body to the bottom having a maximum diameter between 1mm and 50cm with height between 1mm and 10m and a cross section nearly equal to a circle, and this columnar body is used as the column. The maximum diameter of the hole is more preferably between 40Angstrom  and 100000Angstrom . Also, the material of the body is not specifically limited, so far as the diameter of the hole is controllable, but an inorganic porous body such as porous ceramic and porous glass, for example, solid porous glass is preferable. When this type of column is used, a separation process takes place in such a structure that a mobility phase passes in a porous body having a uniform diameter, namely a single-bore porous body. Thus, separation mode is simplified and enough reproducibility is guaranteed.
