A laboratory technique used to separate different substances in a mixture. A gas or a liquid is used to pass the mixture through a column, paper, or special plate that contains absorbing materials. The substances in the mixture are separated based on how far they move through the material. The different substances may be visible to the eye or detected by a special machine.NCI Dictionary of Cancer TermsU.S. National Cancer Institute, 2021
-
A technique for the separation of complex mixtures that relies on the differential affinities of substances for a gas or liquid mobile medium and for a stationary adsorbing medium through which they pass.NCI ThesaurusU.S. National Cancer Institute, 2021
-
Diverse group of techniques used to separate mixtures of substances based on differences in relative affinities for two different media, one a mobile phase and the other a stationary or sorbent phase.CRISP ThesaurusNational Institutes of Health, 2006
