The paper is called the stationary phase while the solvent is referred to as the mobile phase performing a chromatographic experiment is basically a three-step process: 1) application of the sample, 2) developing the chromatogram by allowing the mobile phase to move up the paper, and 3) calculating rf values and. An introduction to paper chromatography (including two way chromatography) and how it works samples of each ink are spotted on to a pencil line drawn on a sheet of chromatography paper some of the ink from the message you would have to re-run the experiment using other amino acids for comparison two way.

Paper chromatography of inks and dyes target audience: 9-12 background and notes: different molecules exert different forces of attraction on each other resulting in different solubilities within different solvents these solubility differences make it possible to separate mixtures into their separate components.
