a laboratory technique used to separate and analyse the components of a mixture

in chromatography, this refers to the liquid or gas that carries the mixture being separated through the column or over the stationary phase; it is responsible for moving the mixture through the stationary phase and is selected based on its ability to dissolve and carry the components of the mixture
