elution

 [e-loo´shun]
in chemistry, separation of material by washing; the process of pulverizing substances and mixing them with water in order to separate the heavier constituents, which settle out in solution, from the lighter.

e·lu·tion

(ē-lū'shŭn),
1. The separation, by washing, of one solid from another.
2. The removal, by means of a suitable solvent, of one material from another that is insoluble in that solvent, as in column chromatography.
3. The removal of antibodies absorbed onto the erythrocyte surface.
Synonym(s): elutriation
[L. e-luo, pp. lutus, to wash out]

elution

[elo̅o̅′shən]
the removal of an absorbed substance from a porous bed or chromatographic column by means of a stream of liquid or gas or the application of heat. The technique may consist of washing a material that dissolves out of just one component of a mixture. The term is also applied to the removal of antibodies or radioactive tracers from erythrocytes. In heat elution of antibodies, red cells in a saline solution are heated to 56° C and then centrifuged. Liquid elution of antibodies usually uses ether as the solvent.

elution

The washing out of a substance from a material into a fluid in which the material is immersed. A coronary artery stent may, for instance, be designed to elute drugs into the bloodstream.
