   Planar chromatography is a separation technique in which the stationary phase is present as or on a plane. The plane can be a paper, serving as such or impregnated by a substance as the stationary bed (paper chromatography) or a layer of solid particles spread on a support such as a glass plate (thin-layer chromatography).

   Picture of HPTLC plate to identify different substances within a sample. High-performance thin-layer chromatography (HPTLC) serves as an extension of thin-layer chromatography (TLC), offering robustness, simplicity, speed, and efficiency in the quantitative analysis of compounds. [1] This TLC-based analytical technique enhances compound ...

4. Thin-layer chromatography - Wikipedia

   en.wikipedia.org/wiki/Thin-layer_chromatography

   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] The sample is deposited on the plate, which ...

   Partition chromatography uses a retained solvent, on the surface or within the grains or fibers of an "inert" solid supporting matrix as with paper chromatography; or takes advantage of some coulombic and/or hydrogen donor interaction with the stationary phase. Analyte molecules partition between a liquid stationary phase and the eluent.

6. 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. The mobile phase is a solution that travels up the ...

   The coupling of chromatography with MS is a well developed chemical analysis strategy dating back from the 1950s. Gas chromatography (GC)–MS was originally introduced in 1952, when A. T. James and A. J. P. Martin were trying to develop tandem separation – mass analysis techniques. [9]
