Chromatography in Greek means to ‘write with colors.’ It is a versatile separation technique developed in 1903 by Mikhail Tswett, a Russian botanist. He separated colorful plant pigments using a column of calcium carbonate. Ever since its discovery, chromatography has evolved as a powerful tool in the lab for the separation and identification of different compounds in a mixture.
