    • A method for the manufacture of at least one sorbent having at least two different groups, which are capable of binding, for the selective binding of a substrate, characterized in that it comprises the steps (i) to (ii): (i) determining at least two groups capable of binding a sorbent from a synthetic or natural first substrate, (ii) respectively applying at least two different groups capable of binding a second synthetic or natural substrate to one respective carrier, thereby forming at least one sorbent, whereby the groups are the same groups of step (i) or are groups that are complementary thereto, and the second substrate of step (ii) is the same or different from the first substrate according to step (i), and whereby the groups are determined such that the contributions of the Gibbs energies of the individual groups to the non-covalent bond with the second substrate yield a negative value of the Gibbs energy ΔG, such that a binding strengthening occurs that results in an improved separation selectivity with respect to at least one substance to be separated off.
    • 一种用于制造具有至少两个能够结合底物的选择性结合的至少两个不同基团的吸附剂的方法，其特征在于其包括步骤（i）至（ii）：（i）确定 至少两个能够结合来自合成或天然的第一底物的吸附剂的组，（ii）分别施加至少两个能够将第二合成或天然底物结合到一个相应载体上的不同基团，由此形成至少一种吸附剂，由此 基团是步骤（i）的相同组或与其互补的基团，并且步骤（ii）的第二底物与根据步骤（i）的第一底物相同或不同，并且由此确定这些基团 单个组的吉布斯能量对与第二衬底的非共价键的贡献产生吉布斯能量＆Dgr; G的负值，使得发生结合强化，导致改进 相对于待分离的至少一种物质的ved分离选择性。

    • A reverse phase chromatographic media selected from media of the formula: [X—C6H4—(O)m—(CH2)n]q—Z and hydrophobic end-capped media of said formula, wherein n is a numeral of from 1 to 4, and m is 0 or 1, and when m is 1 X is selected from the group H, an alkyl group having from 1 to 6 carbon atoms and a phenyl group, and when m is 0 then X is selected from an alkoxy group having from 1 to 6 carbon atoms and a phenoxy group, Z is the backbone of a silica or hydrophilic polymer chromatographic support, and q is a number equal to the number of ligands attached to the backbone of the silica or hydrophobic polymer chromatographic support, with the proviso that when said reverse phase chromatographic media of the formula is not end-capped with hydrophobic groups X is not H when m=1. These novel chromatographic media are prepared by reacting: (a) a chromatographic media support selected from (1) a silica support having hydroxyl groups on the surface of the silica backbone or (2) a hydrophilic polymer support having hydroxyl, amine or imine groups on the surface of the polymer backbone, with (b) a reactant of the formula [X—C6H4—(O)m—(CH2)n]p—Si(Y)4-p wherein p is a numeral of from 1 to 3, Y is a chloro or alkoxy group having from 1 to 4 carbon atoms in the alkoxy group, and m, n and X are as defined above, and optionally end-capping the resulting media by reacting it with a hydrophobic end-capping reactant. The resulting chromatographic media with these ligands attached to the backbone of the silica or hydrophilic polymer support provides chromatographic media that offers analyte separation capability in the aqueous mobile phase.
