  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. 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.

  4. Chromatography - Wikipedia

    en.wikipedia.org/wiki/Chromatography

    Chromatography, pronounced / ˌ k r oʊ m ə ˈ t ɒ ɡ r ə f i /, is derived from Greek χρῶμα chrōma, which means "color", and γράφειν gráphein, which means "to write".". The combination of these two terms was directly inherited from the invention of the technique first used to separate biological pigme

  5. Chiral analysis - Wikipedia

    en.wikipedia.org/wiki/Chiral_analysis

    Chiral chromatographic assay is the first step in any study pertaining to enantioselective synthesis or separation. This includes the use of techniques viz. gas chromatography (GC), high performance liquid chromatography (HPLC), chiral supercritical fluid chromatography (SFC), capillary electrophoresis (CE) [35] and thin-layer chromatography (TLC).

  6. 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]

  7. Separation process - Wikipedia

    en.wikipedia.org/wiki/Separation_process

    Chromatography separates dissolved substances by different interaction with (i.e., travel through) a material. High-performance liquid chromatography (HPLC) Thin-layer chromatography (TLC) Countercurrent chromatography (CCC) Droplet countercurrent chromatography (DCC) Paper chromatography; Ion chromatography; Size-exclusion chromatography (SEC)

  8. 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 .

  9. Forensic chemistry - Wikipedia

    en.wikipedia.org/wiki/Forensic_chemistry

    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.
