"Chromatography is a separation technique. It is mainly used to separate the mixtures.

The following precautions must be maintained during chromatography experiments.

• Pencil should be used instead of a pen to draw thin lines, if we use a pen, it may have a solvent-soluble ink.
• The ink stains can move up of the chromatography paper and then it may give the error values of the experiment.
• Before placing the chromatography paper in the solvent, it must be dry.
• Make sure the paper is dipped in the solvent."
