Using a solid support (like paper) to separate different kinds of molecules is called chromatography.Make sure students do not draw marker lines too close to the crease in the chromatography paper.Stationary Phase. Writing paper is coated so that ink does not run and because of this is less satisfactory.Compounds contained in the sample will stick to the carbon chains in the column, with the most apolar compounds sticking the strongest, and the most polar compounds sticking weakly.A class demonstration gives the students the opportunity to compare and contrast the physical characteristics of a few simple mixtures and solutions.

Criminal investigators use this technology to identify substances such as drugs, blood, ink and other fluids.High-performance liquid chromatography, or HPLC, is a long name for a powerful technique based on the simple fact that individual compounds behave differently in water.
