Title :

QN.1 Yes chromatography is possible to separate mix dyes
QN.2 Advantages & disadvantages:The biggest advantage of column chromatography is that it can usually be scaled to the project at hand. This is especially useful if one is trying to separate and purify a reaction mixture preparing an intermediate in a sequence of reactions. The corresponding disadvantage is the column may take a long time to properly prepare and use.

Thin layer chromatography is usually great for initial analysis and determining the conditions needed for a good separation. Many plates are commercially available and the chromatograms usually do not take a long time to develop. The main disadvantage is the very small amounts of compounds handled. These can be recovered for instrumental analysis, but seldom is there enough for further reaction.
