  • Publication number: 20110023711
    Abstract: The problem to be solved by the present invention is to provide a monolith adsorbent which can adsorb a target sample easily in a short time or regardless of whether the amount of the sample is small or large and extract the sample with a small amount of solvent, and easily secure the sample necessary for analysis, and a method and an apparatus for adsorption and retention using the same. The present invention, as the means for solving the problem, is a monolith adsorbent formed by allowing a monolith structure body to contain an adsorbing material such as activated carbon or graphite, exposing the adsorbing material on the surface of the structure body and further surface-treating the surface of the monolith structure body with a hydrophobic or hydrophilic compound or a resin.

  • Publication number: 20110000279
    Abstract: To use a monolithic silica body in chromatography with a HPLC column or a GC column and to simplify the use thereof as a separation medium, it is intended to provide a method of cladding a main body of a monolithic adsorbent or separating agent with glass so as to protect the outer surface, and to provide a separation medium prepared by the method. To this end, a monolithic silica body alone is formed by molding, and the molding is coated with a glass body; and then the glass body and the monolithic silica body are fused and integrated at the melting temperature of the glass body at an appropriate pressure. The surface of the resulting monolithic silica body clad with glass is strongly protected by the glass, and the homogeneity of the interior of the monolithic silica body is maintained, and thus uniform flow of a sample solution ensures analytical accuracy.
