High-speed Liquid Chromatography of Sugar Acids on An- Ion-exchange Resins
Mixtures of aldonic and aldaric acids are difficult to analyse. Aldonic acids can be separated in a satisfactory way on anion-exchange resins with a solution of sodium chloride as eluent. Under these circumstances, however, aldaric acids show unacceptably long elution times and peak broadening. The ability of aldaric acids to form non-adsorbable complexes with magnesium ions lowers their elutio...
متن کاملDisplacement Chromatography on Synthetic Ion - exchange Resins
In Part 1 of this series of papers (Partridge & Westall, 1949) it was shown that, whilst the baseexchange resin Zeo Karb 215 may be used with success for the separation of the neutral and acidic amino-acids, certain difficulties arise when the separation of basic substances is attempted. These difficulties were traced to the phenolic hydroxyl groups of the resin. Resins of the sulphonated pheno...

9. Accumulation of glutamate also occurred in isolated kidney cortex, spleen, lung and chorion. Six other tissues examined maintained a concentration gradient between tissue and medium, but did not increase the glutamate concentration above the original level. 10. It is pointed out that tissue slices afford a system in which problems of permeability and storage can be studied under controlled c...
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...
