    Abstract: The present invention provides a chromatographic stationary phase material various different types of chromatography. One example chromatographic stationary phase is represented by Formula 1 [X](W)a(Q)b(T)c (Formula 1). X can be a high purity chromatographic core composition. W can be absent and/or can include hydrogen and/or can include hydroxyl on the surface of X. Q can be bound directly to X and can include a first hydrophilic, polar, ionizable, and/or charged functional group that chromatographically interacts with the analyte. T can be bound directly to X and can include a second hydrophilic, polar, ionizable, and/or charged functional group that chromatographically interacts with the analyte. Additionally, Q and T can essentially eliminate chromatographic interaction between the analyte, and X and W, thereby minimizing retention variation over time (drift or change) under chromatographic conditions utilizing low water concentrations.

  • Publication number: 20130131357
    Abstract: The invention relates to a method for preparing silica modified by a silane coupling agent. The method comprises the following steps: preparing a kind of coupling agent sol solution by mixing the solvent, water, catalyst and coupling agent; uniformly dispersing silica into the sol solution by means of ultrasonic dispersion or shear dispersion to achieve a turbid solution with uniform dispersion and ideal particle size; and then stirring the turbid solution at a constant speed to make the coupling agent sol reacting with silica to prepare highly hydrophobic silica modified by the coupling agent through controlling the temperature and reaction time. The coupling agent sol solution is obtained by a sol-gel process and silica is uniformly dispersed in the coupling agent sol solution through combined action of various dynamic means to ensure the sufficient reaction between silica and coupling agent, thus to obtain silica modified by the coupling agent.

  • Publication number: 20130060014
    Abstract: A surface-modified inorganic material and a preparation method thereof. A surface-modified inorganic material is provided which is obtained by allowing an organosilane compound having allyl or an allyl derivative to react with an inorganic material, particularly solid silica or ITO glass, in the presence of an acid and an organic solvent, to introduce an organic group into the inorganic material even at room temperature, as well as a preparation method thereof. The invention can effectively introduce the organic group into the inorganic material even at room temperature, and thus is very effective in introducing compounds having a thermally sensitive functional group, for example, natural compounds or proteins. It is possible to introduce various organic groups into an inorganic material and to separate and purify organic molecule-bonded organosilane compounds using a silica gel column to effectively bond them to inorganic materials.
