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]

One was to compare the profile and elution times of the peak with those of the standards, and the second was to 'spike' the ink by adding 4 nanomoles Of L-dopa and dopamine to the ink sample.
The use of reverse-phase plates has the added advantage of being able to change the elution solvent and obtain a different separation pattern.
So a rinsing step was employed to remove the residual matrix on the micro-column before elution and introducing the eluate to the ICP-MS instrument.
