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 ...
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.
Capillary electrochromatography (CEC) combines the principles used in HPLC and CE. The mobile phase is driven across the chromatographic bed using electroosmosis instead of pressure (as in HPLC). Electroosmosis is the motion of liquid induced by an applied potential across a porous material, capillary tube, membrane or any other fluid conduit.

High performance liquid chromatography (HPLC) High performance liquid chromatography-IR spectroscopy (HPLC-IR) I. Ion Microprobe (IM) Inductively coupled plasma (ICP)
Thermospray is a soft ionization source by which a solvent flow of liquid sample passes through a very thin heated column to become a spray of fine liquid droplets. As a form of atmospheric pressure ionization in mass spectrometry these droplets are then ionized via a low-current discharge electrode to create a solvent ion plasma.
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)
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 ...
