ion-exchange chromatography

…by using the methods of ion-exchange chromatography. In this process, ions are variously adsorbed from solution onto materials with ionic charges on their surface and separated from the rest of the sample. After the dating elements have been isolated, they are loaded into a mass spectrometer and their relative isotopic…

Ion-exchange chromatography (IEC) is a subdivision of liquid-solid chromatography, but its importance is such that it deserves special mention. As the name implies, the process separates ions; the basis of the separation is the varying attraction of different ions in a solution to oppositely charged…

…solid is called ion, or ion-exchange, chromatography. The first such chromatographic separations were reported in 1938 by T.I. Taylor and Harold C. Urey, who used a zeolite. The method received much attention in 1942 during the Manhattan Project as a means of separating the rare earths and

This process is called ion-exchange chromatography. Ion-exchange chromatography is an important tool in chemical analysis because it permits separation of materials that are very difficult to separate by other means. It can be applied to organic and inorganic ions and even to substances that are not ionic. It is…
