How can chromatography be used to identify substances?

Chromatography can be used to determine the RF value of an unknown substance. This RF value when cross-referenced with already known RF values can then be used as a guide to find out a potential range of substances from the origin that it could be. With this alongside other investigative methods, it is possible to identify unknown substances.
