Webb10 sep. 2024 · Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, causing them to separate. WebbThe plate theory of chromatography ﬁ rst attempts to deﬁ ne the chro-matographic process through equations that describe a single equilibration of a single sample between the stationary and mobile phases.
