Note 2. Selection of chromatographic solvent An unknown mixture should be first chromatographed on 20 cm x 5 cm plates with solvent of different polarities to obtain an idea of the polarities of compounds present in the sample and to reduce the possibility of missing any of the sample components. Solvents of low polarity, such a n-hexane, tetrachloroethylene and carbon tetrachloride, cause polar sample constituents to migrate more readily. Solvents of intermediate polarity such as toluene, benzene, chloroform and methyl cellusolve have a greater elutive effect on polar sample components, whereas highly polar solvents such as dioxan, methylene dichloride, ethyl acetate, nitromethane, acetone, lower alcohols and water elute polar sample constituents towards the solvent front, ie. Rf values near unity. Mixtures of 40/60 petroleum spirit and up to 10% (v/v) ethyl acetate are very useful general solvents for the separation of unknown mixtures.
