Chromatographic Methods: Separation of Dyes and Spinach Pigments by Column and Thin Layer Chromatography Organic Chemistry (CHEM 233) Lab Report 1 Methods and Background In this experiment the chemical technique used is chromatography. Chromatography is a method used to separate mixtures in their components. Unlike many other chemical techniques which make use of the differences in the melting and boiling points of the components, chromatography uses the polarity of the components. There are several types of chromatography but for the sake of this experiment, the only two types used are Column chromatography and Thin­Layer chromatography. Column chromatography makes use of two basic components – the solvent and the the absorbent. Often these two are referred t
