What are the two types of stationary phase?
It contains two phases they are stationary and mobile phase. Here the stationary phases are kept fixed and the mobile phase is passed through this stationary phase.
What are stationary phases?
stationary phase, in analytical chemistry, the phase over which the mobile phase passes in the technique of chromatography. Typically, the stationary phase is a porous solid (e.g., glass, silica, or alumina) that is packed into a glass or metal tube or that constitutes the walls of an open-tube capillary.
What is a Pirkle column?
The Pirkle 1-J contains an unusual ß-lactam structure which significantly alters its molecular recognition properties. It is useful for the direct separation of underivatized ß-blocker enantiomers. It can also be used for the separation of the enantiomers of arylpropionic acid NSAIDs, as well as other drugs.
What is chiral stationary phase?
The stationary phase contains a single enantiomer of a chiral compound. The chiral stationary phase can be prepared by attaching a chiral compound to the surface of an achiral support such as silica gel.
What are the 2 phases of chromatography?
Chromatography is a physico-chemical method for separation of compound mixtures, based on the distribution of components between two phases, one of which is stationary (sorbent), and the other, mobile, flowing through a layer of the stationary phase.
Which stationary phase is suitable for separation of chiral compounds?
Common chiral stationary phases used for chiral HPLC columns are polysaccharide, ligand exchange, protein, helical polymers, macrocyclic, and Brush (Pirkle-concept).
How many phases are there in chromatography?
two phases
Chromatography is a physico-chemical method for separation of compound mixtures, based on the distribution of components between two phases, one of which is stationary (sorbent), and the other, mobile, flowing through a layer of the stationary phase.
What are 4 types of chromatography?
There are four main types of chromatography. These are Liquid Chromatography, Gas Chromatography, Thin-Layer Chromatography and Paper Chromatography.
What is the type of chromatography?
Various chromatography methods have been developed to that end. Some of them include column chromatography, thin-layer chromatography (TLC), paper chromatography, gas chromatography, ion exchange chromatography, gel permeation chromatography, high-pressure liquid chromatography, and affinity chromatography [6].
