1. the process of extracting or washing out a substance from a material, especially in chemistry and laboratory procedures such as chromatography.
Usage: technical term commonly used in chemistry and biochemistry

Examples

• The elution of the dye from the chromatography column took several hours.
• Researchers used a salt solution for the elution of proteins from the resin.
• Proper elution technique is critical to obtaining pure samples in laboratory work.
• The elution process removed the absorbed compounds from the activated charcoal.
• Scientists monitored the elution curve to determine when the target molecule was being released.
