The chromatography paper was then placed in the equilibrated chromatography jar and was left there for 30 to 45 minutes in dark or dim lightening conditions or until the separation of the 5 bands is visible. Afterwards. the chromatogram was removed from the jar and hold by the corner until dry. Then. the distance from the origin to the solvent front and to the centre of each band was measured.

Chromatography is the parting of mixtures of chemical substances in pure components and their quantification is a central theme of substance lab work. Only in this manner researchers can properly review the purity of both chemicals and structure of mixtures with different content. The rules of chromatography as used today have as their starting place the botanist Michael Tswett (1872–1919 . . .
