- n. The process of removing materials that are absorbed with a solvent.
from The Century Dictionary and Cyclopedia
- n. A washing out; any process by which bodies are separated by the action of a solvent; specifically, a process of recovering sugar from molasses, which consists in precipitating the sugar as sucrate of lime, insoluble in cold water, and washing it free from soluble impurities.

- n. the process of extracting one material from another by washing with a solvent to remove adsorbed material from an adsorbent (as in washing of loaded ion-exchange resins to remove captured ions); used to obtain uranium ions
It starts to become more difficult for the low intensity peaks, those with low signal-to-noise ratios, or those with a different elution profile e.g. peak tailing.
Wegel had told the court that he had performed two separate tests on the crime-scene semen — “absorption-inhibition” and “absorption-elution.”
Giving testimony in 2000, he said that in his view, it was appropriate to use both absorption-elution and absorption-inhibition in order to determine secretor status.
Absorption-elution, on the other hand, was about 100 times more sensitive.
Perhaps, Roberts speculated, Wegel had then gone on to perform absorption-elution — and only then detected the very low chemical levels that made him assert that the killer might be a weak secretor.
It was only when he used the hypersensitive absorption-elution method that very low levels showed up.
Repeating his insistence that absorption-elution was not hypersensitive, Wegel stood by the evidence he gave at the trial, stating that the worksheets did not suggest that Gary was excluded at all.
A model of chemical fractionation in ice based on differing elution rates for pairs of ions is developed as a proxy for summer melt 1130–1990.
The di-iso-lysergic acid N,N-diethyl amide which remains absorbed on the alumia column as the second fluroescent zone is removed from the column by elution with chloroform.
The more rapidly moving zone is d-lysergic acid N,N-diethylamide which is eluted with about 3000 ml. of the same solvent as above, the course of the elution being followed by watching the downward movement of the more rapidly moving blue fluorescing zone.
