Elution - Wikipedia
In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent: washing of loaded ion-exchange resins to remove captured ions, or eluting proteins or other biopolymers from a gel electrophoresis or chromatography column.
AARL Carbon Stripping System Operation: Elution ...
2016年4月1日 · The stripping of gold from loaded carbon here involves two basic steps; Acid Washing and Elution. The elution step may be further divided into two major stages; carbon preheat and elution proper. Here a separate column is provided for acid washing.

12.2: General Theory of Column Chromatography - Chemistry ...
In this section we develop a general theory that we may apply to any form of column chromatography. Figure 12.6 provides a simple view of a liquid–solid column chromatography experiment. The sample is introduced at the top of the column as a narrow band.
Column Chromatography - Principle, Procedure, Applications ...
What is elution in column chromatography? Elution refers to the chromatographic technique of extracting an adsorbed substance from a solid adsorbing media using a solvent. Q7
Introduction to Liquid Chromatography Principles - Bio-Rad
In affinity chromatography, proteins are commonly eluted from the column by the introduction of a competing ligand or by cleaving the affinity tag and may also be eluted using high-salt buffers or altering pH. Other elution protocols may involve mixing solvents of varying polarity to tune the solubility of each component in the mobile phase.
Column chromatography - Wikipedia
The mobile phase or eluent is a solvent or a mixture of solvents used to move the compounds through the column. It is chosen so that the retention factor value of the compound of interest is roughly around 0.2 - 0.3 in order to minimize the time and the amount of eluent to run the chromatography.
