Answer:

Paper chromatography is a method used to distinguish or separate coloured substance mixtures.

In the image, take an example of colured chemical placed in a glass beaker. If a paper is placed in that chemical, coloured spots are separated and displayed on the chromatogram.

It was founded in 1944 A.D by a scientist called Erwin Cargaff.
