Abstract:
1. A method for separating one or more components of interest from a sample comprising the steps of: a. filtering a sample containing particulates and soluble materials through silica filter media whose surface active groups have reacted with hydrolyzable moieties of one or more silanes, wherein the hydrolysable moieties are selected from the group consisting of hydroxy, aryloxy, amide, methacrylate, mercapto, carbonyl, urethane, pyrrole, carboxy, cyano, aminoacyl, acylamino, alkyl ester, and aryl ester; b. simultaneously capturing particulates and binding a soluble component of interest to the silica filter media; and c. eluting the bound soluble component of interest from the silica filter media.
