Abstract
PURPOSE:To enable a filter to adjust the permeability of fluid by supporting the material removable in a specified condition with the porous filter. CONSTITUTION:The filter 11 confronting to the influent opening of the packing layer 10 of a minicolumn 1 is obtained by treating the porous filter with the material capable of sealing the permeability of fluid. As for the material capable of sealing the permeability of fluid, a natural or a synthetic high molecular material, such as geratin and cellulose, is used. The treatment of filter is ordinarily carried out in such a way that the sealing material is coagulated or deposited in the surface part or the inner part of porous material. The filter 11 sealed by above-mentioned method loses the function of filter and works as a partition. In order to restore the function of the filter 11, the sealing material is to be removed and the permeability is restored.
