        Chromatography as a separation technique in which a mobile phase carrying a mixture is caused to move in contact with a selectively absorbent stationary phase.
        Social and Applied Aspects
        Use of thin-layer chromatography (TLC) in the separation of dyes taken from fibres in forensic work.

        (i) Chromatography
        Chromatography is a technique used to separate the components present within a mixture. Chromatography separates substances by making use of differences in their polarity or molecular size.
        The details of any specific chromatographic method or experiment are not required. Depending on the type of chromatography used, the identity of a component can be indicated either by the distance it has travelled, or by the time it has taken to travel…

        Thin-layer chromatography
        Candidates should be familiar with thin-layer chromatography experimental procedure.
        Rf values can be calculated and under similar conditions a compound will always have the same Rf value within experimental error.
        Since a pure substance will show up as only one spot on the chromatogram, TLC can be used to assess the purity of a product prepared in the lab.
