  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]

    Thin layer chromatography (TLC) is a quick alternative to more complex chromatography methods. TLC can be used to analyze inks and dyes by extracting the individual components. [ 18 ] This can be used to investigate notes or fibers left at the scene since each company's product is slightly different and those differences can be seen with TLC.

  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. Hydrophobicity scales - Wikipedia

    en.wikipedia.org/wiki/Hydrophobicity_scales

    Pliska and his coworkers [27] used thin layer chromatography to relate mobility values of free amino acids to their hydrophobicities. About a decade ago, another hydrophilicity scale was published, this scale used normal phase liquid chromatography and showed the retention of 121 peptides on an amide-80 column. [28]

  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).

  7. Analytical chemistry - Wikipedia

    en.wikipedia.org/wiki/Analytical_chemistry

    In Thin-layer chromatography, the analyte mixture moves up and separates along the coated sheet under the volatile mobile phase. In Gas chromatography, gas separates the volatile analytes. A common method for chromatography using liquid as a mobile phase is High-performance liquid chromatography.

  8. Chiral thin-layer chromatography - Wikipedia

    en.wikipedia.org/wiki/Chiral_thin-layer...

    Chiral thin-layer chromatography is a variant of liquid chromatography that is employed for the separation of enantiomers. It is necessary to use either It is necessary to use either a chiral stationary phase or

  9. Paper chromatography - Wikipedia

    en.wikipedia.org/wiki/Paper_chromatography

    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). This analytic method has three components, a mobile phase, stationary phase and a support medium. The mobile phase is a solution that travels up the stationary phase by capillary action ...
