The purpose of chromatography is to separate out parts of a solution—to isolate substances you might have used paper chromatography in your chemistry lab.
Chemistry : chromatography one uses chromatography to find out the components of a sample which are seperated depending how much soluble these are in particular solvents and hence how far they travel along the chromatography specific rf values of dyes and compounds obtained in the lab. Chromatography: chromatography has this method is very useful when the components of a mixture have almost the same physical and chemical properties and hence can't be separated by other usual methods of separations powered by amrita virtual lab collaborative platform.
