Title :

Chromatography a feasible possible method to separate the bucket of mixed paint.

There are different types of chromatography, such as paper, thin layer, or column chromatography (amongst others), each with its own strengths and weaknesses. Chromatography systems have a stationary phase (which can be solid or liquid) and a mobile phase (usually liquid or gas). In column chromatography both phases are placed in a column container.

Advantages :
Chromatography is advantageous over most other chromatographic techniques because it can be used in both analytical and preparative applications. Not only can column chromatography be used to determine the number of components of a mixture, but it can also be used to separate and purify substantial quantities of those components for subsequent analysis. This is in contrast to paper chromatography, which is solely an analytical method.

Disadvantages :
Chromatography does have its complications. Properly setting up the column (something that will be done for you prior to experiment) requires some technical skill and manual dexterity, and takes some time. Column chromatography is less foolproof than paper chromatography and requires constant attention while the experiment is being performed: collection vessels must be frequently switched and solvent levels need to be topped up.
