Chromatography is a method of separating substances. In school it is often used to separate the light-capturing pigments in plants or to separate amino acids. It is also common to use paper chromatography in schools. We calculate how far the solvent used moves along the chromatogram and we measure the distance each substance has moved. If you divide the distance moved by a substance and divide that by the distance the solvent travelled you get...

Explanation:
Chromatography separates a mixture on the principle that different substance have different speed through an adsorbing medium. So, if two components of a mixture have the same speed through an adsorbing medium mixture cannot be separated by chromatography.
