Paper chromatography,separating coloured inks (vertical streaks). Chromatography is an analytical process that separates a compound into its constituent chemicals. Chromatography paper with the ink on it is dipped vertically in a solvent. Capillary action draws the solvent up through the paper,dissolving the ink. As the solvent travels up the paper it takes the various chemicals in the ink with it,separating them into a series of coloured bands | |
