A chemistry technique
; a type of column chromatography
, used to separate the components of a mixed substance. The substance is held stationary by an inert solid
coated with an inert liquid which is not likely to evaporate
(i.e. is nonvolatile
), while a gas (called an eluant
) flows past it bringing out the components one at a time.
