The present invention provides novel, polymeric supports, methods of making, and methods of using the supports, that have a fluorinated, amidated surface. The supports include polymeric microbeads, thin layers or membranes, plates, monoliths and the like. The supports are useful as packing materials for normal phase, reverse phase, and size exclusion chromatography, and provide high speed separation of analytes with excellent resolution. The fluorinated, amidated surface may include a composition comprising a plurality of repeating units, for example, having the following structure: ##STR00001##
