Chromatography of amino acids on sulfonated polystyrene resins.
The quantitative separation of amino acids by chromatography on columns of starch has sheen described in previous publications (l-3). In extending these investigations, a systematic study has been made of the separations of amino acids by elution analysis on columns of synthetic ion exchange resins. With a sulfonated polystyrene resin, Dowex-50, it has been possible to develop a chromatographic...
متن کاملPreparative Isolation of Amino Acids by Carrier Displacement Chromatography on Ion Exchange Resins* by Donald
Chromatographic separations of amino acids on ion exchange resins may be performed on a preparative scale either by elution (24) or by displacement (5-12). Some of the exceptional resolving power demonstrated in analytical separations by elution techniques (13, 14) disappears when larger columns with relatively higher loads are used (2). Displacement chromatography allows large quantities of so...

متن کاملDual-Column Cation-Exchange Chromatographic Method for f3- AminoisobutyricAcid and /3-Alanine in Biological Samples1
A rapid, automated chromatographic method has been developed for the quantitation of the nucleic acid catabolites f3-aminoisobutyric acid and fl-alanine in urine, serum, and other physiological fluids. The analyses were performed on a modified Beckman 121M amino acid analyzer with dual ion-exchange columns and the use of a single sodium citrate buffer (pH 4.38, 0.20 mol/liter). By carefully mat...
متن کاملIon Exchange Column Performance Model for Separation of Zr(IV) and Hf(IV) in Elution Process
A mathematical model of sorption of Zirconium and Hafnium cations mixture and elution of these ions from a cation exchange resin bed is developed. Sulfuric acid is selected as the eluent for selective separation of Zr and Hf in a packed bed of Dowex cation exchange resin. The column model is a dispersed plug flow model,and assumed to consist of randomly packed synthetic and spherical resin ...
