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.
