What are the advantages and disadvantages of chromatography?

Advantages of Paper Chromatography: Why use paper chromatography? This method is quick to perform and easy to master. It can rapidly determine the number of constituents of a mixture sample. Paper chromatography even allows one to positively identify these constituents. Another advantage of this method is that it requires a relatively small sample and is very inexpensive.

Disadvantages of Paper Chromatography: Some mixtures are very difficult to separate by paper chromatography. Paper chromatography is solely an analytical method, not a preparative one. Because the sample size is so small, it is difficult to perform further analysis after the sample's contents have been chromatographically separated. This is in contrast to methods such as column chromatography, which are frequently use to preparatively separate larger amounts of mixtures. Lastly, paper chromatography can only be used in qualitative analysis. It is not possible to extract meaningful information about the quantitative content of a mixture from a paper chromatogram.
