Elution Volume

Definition - What does Elution Volume mean?

Elution volume is the amount of elution or the volume of elution required to cause the elution process, which is the removal of materials that are absorbed with a solvent. In the elution process, ions are removed or stripped from an ion exchange material by other ions, either because of greater affinity or because of a much greater concentration. Predicting and controlling the order of elution is a key aspect of column chromatography methods.

Corrosionpedia explains Elution Volume

Elution can cause both inhibition and augmentation of corrosion, depending on the surrounding environment. However, in order to do so a sufficient volume of eluent is required to extract one material from another by washing with a solvent.

Given a sufficient elution volume, the elution time is also less, because the elution process becomes more effective as the time decreases between the start of the separation and the time at which the solute elutes. Under standard conditions for a known mix of solutes using a certain technique, the elution volume may provide enough information to identify solutes.

Elution causes localized corrosion in stainless steel at high temperatures because the elution speed of iron atoms is higher.
