2. High-performance liquid chromatography - Wikipedia

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

   Modern HPLC systems have been improved to work at much higher pressures, and therefore are able to use much smaller particle sizes in the columns (<2 μm). These "ultra high performance liquid chromatography" systems or UHPLCs, which could also be known as ultra high pressure chromatography systems, [53] can work at up to 120 MPa (17,405 lbf/in ...

3. Monolithic HPLC column - Wikipedia

   en.wikipedia.org/wiki/Monolithic_HPLC_column

   A monolithic HPLC column, or monolithic column, is a column used in high-performance liquid chromatography (HPLC). The internal structure of the monolithic column is created in such a way that many channels form inside the column. The material inside the column which separates the channels can be porous and functionalized.

4. 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 ...

5. Chromatography - Wikipedia

   en.wikipedia.org/wiki/Chromatography

   Liquid chromatography (LC) is a separation technique in which the mobile phase is a liquid. It can be carried out either in a column or a plane. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high-performance liquid chromatography.

6. Chromatography column - Wikipedia

   en.wikipedia.org/wiki/Chromatography_column

   Chromatography columns of different types are used in both gas and liquid chromatography: Liquid chromatography: Traditional chromatography columns were made of glass. Modern columns are mostly made of borosilicate glass, acrylic glass or stainless steel. To prevent the stationary phase from leaking out of the column interior a polymer ...

7. Countercurrent chromatography - Wikipedia

   en.wikipedia.org/wiki/Countercurrent_chromatography

   A high-performance countercurrent chromatography system. Countercurrent chromatography (CCC, also counter-current chromatography) is a form of liquid–liquid chromatography that uses a liquid stationary phase that is held in place by inertia of the molecules composing the stationary phase accelerating toward the center of a centrifuge due to centripetal force [1] and is used to separate ...
