FAQs on Paper Chromatography
What are the limitations in the use of paper chromatography?
Paper Chromatography is a very cheap, simple and highly sensitive technique but large quantity of sample cannot be applied on paper chromatography. In quantitative analysis paper chromatography is not effective. Complex mixture cannot be separated by paper chromatography.
What does paper chromatography depend on?
Paper chromatography depends upon two non-mixing liquid phases, the solvent and the water bound to the cellulose molecules of the filter paper. When a substance which is soluble in the two non-mixing solvents is exposed simultaneously to both, it will partition itself between them. The process in which substances move in one medium when they are placed in another medium is called partitioning.
Why water is not used in paper chromatography?
Water is polar, so any non-polar substance dissolved in it will dissolve in the water. When the water travels up the paper, it will take any non-polar substance dissolved in it with it. This means that if you were trying to separate out a mixture of non-polar and polar substances, they would all travel up the paper together and you wouldn’t be able to tell which was which. The problem here is that all compounds dissolve equally well in water, so many of your compounds would remain in the aqueous layer on top of the stationary layer, and not move at all.
