2. High-performance liquid chromatography - Wikipedia

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

   The theory of high performance liquid chromatography-HPLC is, at its core, the same as general chromatography theory. [41] This theory has been used as the basis for system-suitability tests, as can be seen in the USP Pharmacopaeia, [ 42 ] which are a set of quantitative criteria, which test the suitability of the HPLC system to the required ...

3. High-performance thin-layer chromatography - Wikipedia

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

   The spot capacity (analogous to peak capacity in HPLC) can be increased by developing the plate with two different solvents, using two-dimensional chromatography. [8] The procedure begins with development of a sample loaded plate with first solvent. After removing it, the plate is rotated 90° and developed with a second solvent.

4. Liquid chromatography–mass spectrometry - Wikipedia

   en.wikipedia.org/wiki/Liquid_chromatography...

   Liquid chromatography–mass spectrometry (LC–MS) is an analytical chemistry technique that combines the physical separation capabilities of liquid chromatography (or HPLC) with the mass analysis capabilities of mass spectrometry (MS). Coupled chromatography – MS systems are popular in chemical analysis because the individual capabilities ...

5. Chromatography - Wikipedia

   en.wikipedia.org/wiki/Chromatography

   Fast protein liquid chromatography (FPLC), is a form of liquid chromatography that is often used to analyze or purify mixtures of proteins. As in other forms of chromatography, separation is possible because the different components of a mixture have different affinities for two materials, a moving fluid (the "mobile phase") and a porous solid ...

6. Protein purification - Wikipedia

   en.wikipedia.org/wiki/Protein_purification

   High performance liquid chromatography or high pressure liquid chromatography is a form of chromatography applying high pressure to drive the solutes through the column faster. This means that the diffusion is limited and the resolution is improved. The most common form is "reversed phase" HPLC, where the column material is hydrophobic.

7. 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 ...

9. Atmospheric-pressure chemical ionization - Wikipedia

   en.wikipedia.org/wiki/Atmospheric-pressure...

   Atmospheric pressure chemical ionization chamber cross section. Atmospheric pressure chemical ionization (APCI) is an ionization method used in mass spectrometry which utilizes gas-phase ion-molecule reactions at atmospheric pressure (10 5 Pa), [1] [2] commonly coupled with high-performance liquid chromatography (HPLC).
