2. Paper chromatography - Wikipedia

   en.wikipedia.org/wiki/Paper_chromatography

   Paper chromatography is an analytical method used to separate coloured chemicals or substances. [1] It is now primarily used as a teaching tool, having been replaced in the laboratory by other chromatography methods such as thin-layer chromatography (TLC). The setup has three components.

3. Thin-layer chromatography - Wikipedia

   en.wikipedia.org/wiki/Thin-layer_chromatography

   Thin-layer chromatography (TLC) is a chromatography technique that separates components in non-volatile mixtures. [1] It is performed on a TLC plate made up of a non-reactive solid coated with a thin layer of adsorbent material. [2] This is called the stationary phase. [2]

5. Chromatography - Wikipedia

   en.wikipedia.org/wiki/Chromatography

   Paper chromatography is a technique that involves placing a small dot or line of sample solution onto a strip of chromatography paper. The paper is placed in a container with a shallow layer of solvent and sealed. As the solvent rises through the paper, it meets the sample mixture, which starts to travel up the paper with the solvent.

   [5] [6] However, flat-bottom chambers and horizontal-development chambers are also used for specific compounds. A general mechanism for the HPTLC device goes as follows. [5] A fitted filter paper is placed in the rear trough of the chamber and the mobile phase is poured through the rear trough to ensure complete solvent absorption of the filter ...

8. Two-dimensional chromatography - Wikipedia

   en.wikipedia.org/wiki/Two-dimensional_chromatography

   The earliest form of 2D-chromatography came in the form of a multi-step TLC separation in which a thin sheet of cellulose is used first with one solvent in one direction, then, after the paper has been dried, another solvent is run in a direction at right angles to the first.
