Chromatography is a technique used to separate the different components in a mixture.
There are column chromatography and paper chromatography.
Chromatography is used to
*separate and identify the components in petroleum
*detect,separate and identify drugs in blood or urine sample
*detect herbicides in vegetables
*separate and identify amino acids
*separate antibiotics from mushroom
*separate colour pigments from plant tissues
*identify inorganic substances in alloys or minerals

Chromatography is the collective term for a family of laboratory techniques for the separation of mixtures. It involves passing a mixture which contains the analyte through a stationary phase, which separates it from other molecules in the mixture and allows it to be isolated.

Separating a mixed compound, based on its components' solubilities, size, affinities, etc. There is a variety of media you can use, but you should google this to get more in-depth info, based on the type you are performing (Thin-Layer, size exclusion, HPLC, etc.)
Good luck!

any of various techniques for the separation for a gas or liquid mobile medium and for a stationary absorbing through which they pass, such as paper, gelatin, or magnesia.

Simplest terms, its separation of molecules by their physical properties (charge, pH, size, etc.)
