Optimizing Cation to Anion Resin Ratio in Mixed-Bed Ion Exchange

Weak anion and cation exchange mixed-bed microcolumn for protein separation.

To separate proteins with a wide distribution of pIs under the conditions compatible to online tryptic digestion (with preferable pH=8.0), weak anion and cation exchange chromatography (WAX/WCX) mixed-bed microcolumn has been developed. With a mixture of five proteins with pIs ranging from 4.2 to 11.4, the effect of WAX/WCX ratio on the separation performance was investigated, and an optimum pa...

Carboxylic cation exchange resin effects in dogs.

Reports describing trials of exchange resins in removing cations from the gastrointestinal tract of experimental animals have been limited to toxicity studies and to measurements of the relative magnitudes of the oral intake and the stool output (1-3). In the experiments presented in this paper changes in serum, urine, and stool components, as well as the external and internal balances of certa...

Procedure to Reduce Sulphite in Wine with Anion-exchange Resin

HORÁK, M., HÍC, P., TOMÁNKOVÁ, E., BALÍK, J.: Procedure to reduce sulphite in wine with anion-exchange resin. Acta univ. agric. et silvic. Mendel. Brun., 2012, LX, No. 8, pp. 79–86 The aim of this experiment was to eliminate SO2 ions present in wine using the anion-exchanger resins. To compare the eff ectiveness, 2 following strongly basic anion-exchange resin were used. When activated, the sod...
