    Abstract: A strong anion exchange composition useful in monophosphate nucleotide isomer separations is comprised of an inert porous particle having a silyl alkyl ammonium compound fixedly attached by a covalent silicon-oxygen-silicon bond to the surface thereof. A process for synthesizing the strong anion exchange composition in an aqueous solvent is disclosed together with methods for separation of monophosphate nucleotide isomers, highly phosphorylated nucleotides and aldopentose carbohydrates using a column packed with this strong anion exchange composition.

    Abstract: An ion exchange composition comprising an insoluble substrate of a synthetic resin having ion exchanging sites at least on its available surface; and a finely divided, insoluble material comprising synthetic resin particles of from about 0.1 to about 5 microns median diameter (with respect to volume) having, at least on their outer surfaces, ion exchanging sites which attract the ion exchanging sites of the substrate, irreversibly attached as a monolayer to the available surface of the substrate. The composition is used for removal and separation of ions, and is especially useful in liquid ion exchange chromatography. For example, a chromatographic separation of halide ions is effected with high speed and resolution by contacting an aqueous solution thereof with a bed of the ion exchange composition which consists of surface sulfonated resin beads of a styrene-divinylbenzene copolymer to the surface of which is irreversibly attached a monolayer of quaternary ammonium-bearing styrene-divinylbenzene copolymer resin particles in the hydroxy form, and then eluting the bed with an aqueous sodium hydroxide solution.
