WebChromatography column 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. WebIon chromatography (IC) is a widely used analytical technique for the separation and determination of anionic or cationic analytes in various sample matrices. It is performed in several separation and detection modes today. IC with suppressed conductivity detection remains the most widely practiced form of the technique.
