CHROMATOGRAPHY Chromatography basically involves the separation of mixtures due to differences in the distribution coefficient (equilibrium distribution) of sample components between 2 different phases. One of these phases is a mobile phase and the other is a stationary phase

LIQUID COLUMN CHROMATOGRAPHY A sample mixture is passed through a column packed with solid particles which may or may not be coated with another liquid. With the proper solvents, packing conditions, some components in the sample will travel the column more slowly than others resulting in the desired separation
