Title :

1.Chromatography is not a feasible method.
2.Advantages:
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.

Disadvantages:
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


3

gas chromatography

liquid chromatography

affinity chromatography

paper chromatography

ion exchange chromatography
