2. Gas chromatography - Wikipedia

   en.wikipedia.org/wiki/Gas_chromatography

   The invention of gas chromatography is generally attributed to Anthony T. James and Archer J.P. Martin. [6] [7] Their gas chromatograph used partition chromatography as the separating principle, rather than adsorption chromatography. The popularity of gas chromatography quickly rose after the development of the flame ionization detector. [8]

3. Chromatography - Wikipedia

   en.wikipedia.org/wiki/Chromatography

   Gas chromatography is based on a partition equilibrium of analyte between a solid or viscous liquid stationary phase (often a liquid silicone-based material) and a mobile gas (most often helium). The stationary phase is adhered to the inside of a small-diameter (commonly 0.53 – 0.18mm inside diameter) glass or fused-silica tube (a capillary ...

4. High-performance liquid chromatography - Wikipedia

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

   The partition coefficient principle has been applied in paper chromatography, thin layer chromatography, gas phase and liquid–liquid separation applications. The 1952 Nobel Prize in chemistry was earned by Archer John Porter Martin and Richard Laurence Millington Synge for their development of the technique, which was used for their ...

5. Separation process - Wikipedia

   en.wikipedia.org/wiki/Separation_process

   Affinity chromatography; Centrifugal partition chromatography; Gas chromatography and Inverse gas chromatography; Crystallization; Decantation; Demister (vapor), removes liquid droplets from gas streams; Distillation, used for mixtures of liquids with different boiling points; Drying, removes liquid from a solid by vaporization or evaporation

6. Reversed-phase chromatography - Wikipedia

   en.wikipedia.org/wiki/Reversed-phase_chromatography

   Reversed-phase liquid chromatography (RP-LC) is a mode of liquid chromatography in which non-polar stationary phase and polar mobile phases are used for the separation of organic compounds. [ 1 ] [ 2 ] [ 3 ] The vast majority of separations and analyses using high-performance liquid chromatography (HPLC) in recent years are done using the ...

7. Headspace gas chromatography for dissolved gas measurement

   en.wikipedia.org/wiki/Headspace_Gas...

   Dissolved gases also occur as a result of human contamination from fuel and chlorinated spill sites. As such, headspace gas chromatography offers a method for determining if there is natural biodegradation processes occurring in contaminated aquifers. [5] For example, fuel hydrocarbons will break down into methane. Chlorinated solvents such as ...

8. Supercritical fluid chromatography - Wikipedia

   en.wikipedia.org/wiki/Supercritical_fluid...

   Supercritical fluid chromatography (SFC) [1] is a form of normal phase chromatography that uses a supercritical fluid such as carbon dioxide as the mobile phase. [2] [3] It is used for the analysis and purification of low to moderate molecular weight, thermally labile molecules and can also be used for the separation of chiral compounds.

9. 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]
