Chromatography is a method used to separate components of a mixture.
In the case of black ink, put a dot of ink about 3 cm from the end of a strip of chromatography paper. Place the first .5 cm of the end of the strip in a solvent such as an alcohol. As the liquid alcohol climbs up the paper strip, it drags along the components of the ink, the more soluble components (pigments) will travel furthest on the strip, the least soluble pigments will trail behind resulting in the separation of the pigments
