What are the advantage and disadvantage of descending method of paper chromatography?

Advantage: The separation between the spots on the chromatogram will be greater.
Disadvantage: Separation may not be complete as the solvent will travel a longer distance due to gravitational pull.

Three forms of chromatography.
  • Paper chromatography.
  • Liquid chromatography.
  • Gas chromatography.
Basically, liquid chromatography involves the use of liquids that may incorporate hydrophilic, insoluble molecules, while gas chromatography involves the use of a gas to separate the substances being analysed.
