### Elution an overview ScienceDirect Topics

The elution time expressed in real time or actual volume varies depending on the individual column, its age, or the batches of buffers used. To alleviate day-to-day and column-to-column variations of elution positions, we adopt the concept of ‘Glucose units (GU)’ which is the representation of elution time, for example, 8.5, 10.3 (in min), as related to the elution position of homologous

### Elution Wikipedia

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 adsorbent in a liquid chromatography column. The adsorbent, a solid phase, is a powder which is

### What is an Elution? Definition from Corrosionpedia

Sep 09, 2014· Elution occurs by the interaction of a metal with greater ionic affinity with another metal of lesser affinity. This is most clearly demonstrated in the process of column chromatography, which is performed by washing the metal with a solvent. A significant concentration of ion-exchange resins are used to remove unwanted ions from a substrate metal

### Chromatography Elution chromatography Britannica

Elution chromatography This method, employed with columns, involves solute migration through the entire system and solute detection as it emerges from the column. The detector continuously monitors the amount of solute in the emerging mobile-phase stream—the eluate—and transduces the signal, most often to a voltage, which is registered as a peak on a strip-chart recorder .
