The column of the anion exchange chromatographic analysis, the separation of anions and advantages of the exchange of ions corresponding

摘要

The invention relates to a column of chromatographic analysis, a method of separation of anions, and a method for the exchange of ions. According to the invention, the lining of the column comprises a substrate of the particles not swelling having, at least on their surfaces which are accessible, the sites of exchangers of cations, these particles having a diameter of 1 to 75 microns, and a coating liquid anion exchanger and is active in the plane by chromatography, which is fixed in the irreversible manner on the surfaces that are accessible of the particles, this coating liquid being constituted by a resin aminee hydrophilic, soluble in water and of which present the anion exchangers exerting a pull on the sites of exchangers of cations, accessible, located on the particles, this coating liquid being retained by the links electrostatic on the surfaces of these particles.
