		DISCUSSION Paper chromatography is an important separation technique that depends upon differences in how strongly the dyes are adsorbed onto the paper (stationary phase) and how soluble the dyes are in the developing solvent (mobile phase).
		Paper chromatography is a method of identifying the components of a mixture by treating them with a solvent and observing how they "travel" different distances on absorbent paper.
		The stationary phase in paper chromatography is the strip or piece of paper that is placed in the solvent.

	Chemical Engineering - T-Shirt Chromatography
		Although there are several different types of chromatography, in each case a substance is placed onto or into a medium and a solvent is passed through the test substance.
		In chromatography science, the solvent is called "the mobile phase" or "the carrier fluid" and the medium is called "the stationary phase".
		Chromatography also is used to synthesize new products since it can separate a pure substance from a complex mixture with great precision.

		The paper is then dipped in to a suitable solvent, such as ethanol or water, and placed in a sealed container.
		The solvent moves up the paper by capillary action, which occurs as a result of the attraction of the solvent molecules to the paper and to one another.
		In some cases, paper chromatography does not separate pigments completely; this occurs when two substances appear to have the same values in a particular solvent.
