👉 Elution is a process in chromatography that involves the separation of two phases by means of an exchange between them. In other words, it refers to the process of removing one phase from another, which is typically achieved through the action of a solvent or reagent on the phase that has been separated. This can be done using different methods such as chromatographic elution, where one phase (e.g., the solute) is eluted by means of an exchange agent, while the other phase
