What is meant by the term chromatography?
Word chromatography (Greek: Chroma = Colour + graphy = wirting), This technique was used to separate the coloured components only from the mixture in the beginning. But nowadays it is used for other mixtures also.
The process in which a chemical mixture carried by a liquid or gas is separated into components as a result of differential distribution of the solutes as they flow around or over a stationary liquid or solid phase.
