Paper chromatography is a simple and cost-effective separation technique that separates and identifies different components in a mixture. [1-4] In paper chromatography, a specialized paper acts as the stationary phase, while a liquid solvent is the mobile phase. The mixture to be analyzed is applied to the paper.
Paper chromatography - Wikipedia
Paper chromatography is one method for testing the purity of compounds and identifying substances. Paper chromatography is a useful technique because it is relatively quick and requires only small quantities of material. Separations in paper chromatography involve the principle of partition.
