CHROMATOGRAPHIC ION-EXCHANGE AND CHANGE-PARTNER REACTIONS - NEW MECHANISMS CONCERNING ION-ION INTERACTIONS OF INORGANIC-COMPOUNDS IN SEPHADEX G-15 COLUMNS

This review describes ion-exchange and change-partner reactions, the n ew mechanisms concerning ion-ion interactions of inorganic compounds, during elution in Sephadex G-15 column. These reactions were revealed by observing the elution profiles of all of the ions employed when sod ium or potassium chloride was eluted with sodium or potassium phosphat e buffer in Various sample-eluent combinations. The general conditions under which the reactions occur are discussed. (C) 1997 Elsevier Scie nce B.V.
