本発明はカラムクロマトグラフィー用カラム特に高速液
体クロマトグラフィー用カラムに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to columns for column chromatography, particularly columns for high performance liquid chromatography.

ルターの孔に充填剤がつまるために、カラム内の圧力が
上昇し使用できなくなることがあった。In recent years, high performance liquid chromatography has made remarkable progress and is now widely used for the separation, quantification and analysis of various mixtures. The column used for this chromatography has filters at both ends, but it is suitable when used with a backing of hard packing material with a particle size larger than the pore size of the filter. If the diameters are non-uniform, the pores of the filter may be clogged with filler, which may increase the pressure inside the column and make it unusable.

径が小さくなるとカラム内の圧力が増加し、充填剤を圧
力で押しつぶしてしまうという二律背反がおこる。The reason why the packing material gets clogged in the filter is because the pore size of the filter is relatively large compared to the diameter of the packing material.If the pore size of the filter is made small, the packing material becomes boring, but if the pore size is made small, the inside of the column becomes clogged. A trade-off occurs in that the pressure increases and the filler is crushed by the pressure.
本発明者らは、上記の問題を克服すべく鋭意研究の結果
、本発明に至ったのである。The present inventors conducted extensive research to overcome the above-mentioned problems, and as a result, they arrived at the present invention.
すなわち、本発明はカラムの両端又は片端に二層構造を

ある。That is, the present invention has a filter with a two-layer structure at both ends or one end of the column, the inner filter has a smaller pore size than the packing material, and the outer filter has a pore size that is 1 part of the inner diameter of the column.
The present invention relates to a column for high performance liquid chromatography characterized by having a pore size of 15 to 1/10000017).

る。Among the filters having a two-layer structure of the present invention, the inner filter that comes into contact with the packing material is a porous filter whose pores are smaller than the particle size of the packing material, and the thickness of the filter is 1/10 of the inner diameter of the column. It is preferably from 1/10000 to 1/10000, and more preferably from 1/100 to 1/10000. 1/1
If it is thicker than 0, the void volume will be large, which is preferable.
% less than 1/10000 is not preferable because the strength is weak. The material for the inner filter is an organic or inorganic material that does not deteriorate due to the elution solvent or the elution compound.

侵されるものであってはならない。The pore size, thickness, and material of the outer filter should be good enough to reinforce the inner filter.The pore size of the O filter should be 15 to 1/10,000 of the column inner diameter.
0 is preferable, and the thickness is 1/2 to 1 with respect to the inner diameter of the column.

Ceramic or the like can be used, but it must not be attacked by the elution solvent or the elution compound.

ングでき、しかも長期間使用できる利点を有する。In the column of the present invention having a double-layered filter as described above, the pores of the inner filter are relatively small, so that the packing material does not become clogged, and the thickness is small, so no pressure is applied inside the column tube. Furthermore, by having a two-layer structure in which the inner filter is reinforced with an outer filter having a roughness of about 0, it is possible to easily back a soft filler or a filler with a wide particle size distribution, and it has the advantage of being usable for a long period of time.
