In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent; as in washing of loaded ion-exchange resins to remove captured ions. In a liquid chromatography experiment, for example, an analyte is generally adsorbed, or "bound to", an … See more The eluent or eluant is the "carrier" portion of the mobile phase. It moves the analytes through the chromatograph. In liquid chromatography, the eluent is the liquid solvent; in gas chromatography, it is the carrier gas. See more The eluate is the analyte material that emerges from the chromatograph. It specifically includes both the analytes and solutes passing … See more Antibody elution is the process of removing antibodies that are attached to their targets, such as the surface of red blood cells. Techniques include using heat, a freeze/thaw … See more • Chemistry glossary • Eluotropic series See more The "elution time" of a solute is the time between the start of the separation (the time at which the solute enters the column) and the time at which the solute elutes.
