Editing Chromatography (section)

==Etymology and pronunciation==
Chromatography, pronounced {{IPAc-en|ˌ|k|r|əʊ|m|ə|ˈ|t|ɒ|g|r|ə|f|i}}, is derived from [[Ancient Greek|Greek]] χρῶμα ''chrōma'', which means "[[color]]", and γράφειν ''gráphein'', which means "to write". The combination of these two terms was directly inherited from the invention of the technique first used to separate [[biological pigment]]s.<ref name="OnlineEtymDict">{{cite OEtymD|chromatography}}</ref>
