↑ The first report of Tsvet's discovery was published in 1905:
Tswett, M. S. (1905) "О новой категории адсорбционных явлений и о применении их к биохимическому анализу" (O novoy kategorii adsorbtsionnykh yavleny i o primenenii ikh k biokkhimicheskomu analizu" (On a new category of adsorption phenomena and on its application to biochemical analysis)), Труды Варшавского общества естествоиспытателей, отделении биологии (Trudy Varshavskago Obshchestva Estestvoispytatelei, Otdelenie Biologii (Proceedings of the Warsaw Society of Naturalists [i.e., natural scientists], Biology Section)), vol. 14, no. 6, pp. 20–39 (Note: Tsvet submitted his manuscript in 1903; however, it was not published until 1905.)
The word "chromatogram" first appeared in print in 1906:
Original: " Wie die Lichtstrahlen im Spektrum, so werden in der Calciumkarbonatsäule die verschiedenen Komponenten eines Farbstoffgemisches gesetzmässig auseindergelegt, und lassen sich darin qualitativ und auch quantitativ bestimmen. Ein solches Präparat nenne ich ein Chromatogramm und die entsprechende Methode, die chromatographische Methode."
Translation: Like light rays in a spectrum, so the different components of a mixture of pigments are dispersed in the calcium carbonate column following a set pattern, and [they] can be determined in there qualitatively as well as quantitatively. I call such a preparation a "chromatogram" and the corresponding method, the "chromatographic method".
