Here is a video which shows a paper chromatography experiment which was conducted to separate the pigments found in a black overhead marker. The different colors of pigments have different solubilities based on their polarity. The blue pigment has a greater solubility in water so it moves faster (goes higher) through the chromatography paper.R f value of each of the compounds (spot) can be worked out and by comparing these with the known R f value of different compounds, the compounds can be identified.. Chromatography Technique # 2. Thin Layer Chromatography: Thin layer chromatography is similar to paper chromatography for identification, separation and purification of components of a mixture.A paper chromatogram is produced by placing a sample of the mixture to be separated near one end of a piece of chromatography paper (the “stationary phase”). The paper is placed into a container so that the paper hangs free without touching the walls of the container. A solvent, the “mobile phase,” is placed into the container.
* Paper is then placed in contact with a solvent solution, at its bottom. * Solvent is drawn up through the paper due to capillary action. * As solvent hits the spot, it dissolves many of the pigments. * Some pigments have a greater attraction for the chromatography paper, so they move a lesser distance. The individual samples do not get diffused as compared to paper chromatography hence sensitivity of detection is more. The components which are separated can be recovered easily by scratching the powdery coating of plate and quantitative separation of spots or zone are possible.

The separation takes place by capillarity, which pulls the substances up the paper at different rates depending on their molecular weight (size), causing them to show up as colored streaks.
Key Concepts I: Plant Pigment Chromatography Paper chromatography is a technique used to separate a mixture into its component molecules. The molecules migrate, or move up the paper, at different rates because of differences in solubility, molecular mass, and hydrogen bonding with the paper. Thus, 25 g of adsorbent will provide a better separation in a 1 cm diameter column than in a 2 cm diameter column. Experimental aspects of column chromatography: The best conditions for running the separation may be determined by experimental tlc (see above section). This will indicate the best adsorbent a nd the best solvent for the separation.
