Uses Paper Chromatography

1. Among all the chromatography methods paper chromatography is an inexpensive and rapid method that provides graphic and clear results.
2. Used as a qualitative method for identifying the components in a mixture in drug analysis and cosmetics also.
3. The separated spots on the finished and dried chromatogram can be cut out and re-dissolved to obtain a pure sample of component of the sample mixtures.
4. Used in several scientific studies in identification of unknown organic and inorganic compounds from a mixture.
5. In forensic studies paper chromatography is used in crime scene investigation and DNA and RNA sequencing along with other studies.
6. Paper chromatography is used as an analytical chemistry technique for identifying and separating colored mixtures like pigments.
7. Sugars, amino acids, lipids and nucleic acids and other biomolecules can be easily identified by spraying with appropriate reagents to detect these specific compounds.
8. Paper chromatography can be reproduced easily as long as the conditions are controlled and maintained.
