ion-exchange chromatography
Quick Summary
Ion-exchange chromatography is a laboratory technique used to separate and analyze mixtures of ions and other charged substances. It utilizes ion-exchange resins packed into a column. These resins have charged sites that attract and bind ions from a solution passing through the column.
Different ions bind to the resin with varying strengths. By carefully controlling the solution's composition, such as pH and the presence of complexing agents, these bound ions can be selectively released (eluted) from the column. This separation process is valuable for analyzing complex biological molecules like amino acids and nucleic acids, as well as for separating inorganic ions like rare earth elements and various metal ions. The technique is a crucial tool in chemical analysis and has applications in fields ranging from clinical diagnosis to environmental monitoring.12

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…
