Samples of each ink are spotted on to a pencil line drawn on a sheet of chromatography paper. Why do we use pencil for paper chromatography Because most pens have pigmentsinks which will dissolve in the chromatography solvent. The solvent is below the level of the sample spots.
The easiest way to find the answer to this question is to try it with various inks from various pens as well as marks from several pencils.
Paper chromatography is used to separate mixtures of soluble substances. For our purposes chromatography is the practice of putting fountain pen ink on a highly absorbent piece of paper and watching the different compounds in the ink separate as they travel up the paper at varying speeds. 1 Why is a pencil used to mark the chromatogram and not a ballpoint or ink pen. So basically a TLC plate is to do chromatography. In paper chromatography a starting line in drawn on the paper in pencil pencil so that it does not dissolve in the solvent and affect the results.
