Title :

DISADVANTAGE
These are some disadvantages of using paper chromatography:

1. It can be used as a preparative technique because we can't aplly a large sample quantity;

2. It can't be used in quantitative analysis;

3. and doesn't allow the separation of complex mixtures.

4.this is one of oldest method
ADVANTAGE
It's less expensive to perform, and you can do "two way" chromatography by running a chromatograph in one solvent, letting the paper dry, turning it 90 degrees and running a second chromatograph in a different solvent. Thin layer chromatography is faster and more accurate, so it's more popular now.
