  2. 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]

  3. Thin layer extraction - Wikipedia

    en.wikipedia.org/wiki/Thin_Layer_Extraction

    Thin layer extraction is a time-periodic reactive liquid extraction process that provides excellent mass transfer while maintaining phase separation. [1] It is performed via a periodic batch production process that controls the time of each chemical reaction .

  4. High-performance thin-layer chromatography - Wikipedia

    en.wikipedia.org/wiki/High-performance_thin...

    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 resolution for quantitative analysis.

  5. Two-dimensional chromatography - Wikipedia

    en.wikipedia.org/wiki/Two-dimensional_chromatography

    Gas chromatography-mass spectrometry (GC-MS) is a two-dimensional chromatography technique that combines the separation technique of gas chromatography with the identification technique of mass spectrometry. GC-MS is the single most important analytical tool for the analysis of volatile and semi-volatile organic compounds in complex mixtures. [7]

  6. Chromatography - Wikipedia

    en.wikipedia.org/wiki/Chromatography

    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).
