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 ...
The theory of high performance liquid chromatography-HPLC is, at its core, the same as general chromatography theory. This theory has been used as the basis for system-suitability tests, as can be seen in the USP Pharmacopaeia, [35] which are a set of quantitative criteria, which test the suitability of the HPLC system to the required analysis ...
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 ...
In order to improve separation efficiency and peak resolution, ultra performance liquid chromatography (UHPLC) can be used instead of HPLC. This LC variant uses columns packed with smaller silica particles (~1.7 μm diameter) and requires higher operating pressures in the range of 310000 to 775000 torr (6000 to 15000 psi, 400 to 1034 bar).
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.
June 13, 2024 at 4:29 PM. The Trump campaign and the Biden administration offered a new outreach to the business world Thursday that crystallized their different promises to corporate America ...
Chromatography software is called also Chromatography Data System. [1] It is located in the data station of the modern liquid, gas or supercritical fluid chromatographic systems. This is a dedicated software connected to an hardware interface within the chromatographic system, which serves as a central hub for collecting, analyzing, and ...
