Gel exclusion chromatography

Gel Exclusion Chromatography (also called molecular exclusion chromatography, size exclusion chromatography, or gel filtration chromatography) is a low resolution isolation method that employs a cool trick. This involves the use of beads that have tiny tunnels in them that each have a precise size Gel permeation chromatography (GPC) is a type of size exclusion chromatography (SEC), that separates analytes on the basis of size, typically in organic solvents. The technique is often used for the analysis of polymers.As a technique, SEC was first developed in 1955 by Lathe and Ruthven. The term gel permeation chromatography can be traced back to J.C. Moore of the Dow Chemical Company who.

Gel filtration chromatography can define as the method of chromatography that makes the use of porous gel beads of specific porosity to isolate components depending upon their molecular sizes. This technique principally retains or excludes particles based on size difference , that's why it is also known as size exclusion or gel exclusion. Gel permeation chromatography/size exclusion chromatography is a type of high performance liquid : chromatography (LC). 2. GPC/SEC can be performed in a wide range of solvents. From non-polar organics to aqueous applications. 3.

Gel filtration chromatography (also known as size exclusion chromatography, molecular sieve chromatography, or gel permeation chromatography) is based on the differential distribution of the components in a sample between the mobile and stationary phases. Specifically, in gel filtration chromatography, this differential distribution depends on the size and shape of the components The size-exclusion limit of the gel filtration resin bed is also important. For typical desalting and buffer exchange applications (as opposed to other types of size-exclusion chromatography), choosing a resin with size-exclusion limits (MWCO) between 2000 and 7000 is usually best Size Gel filtration (GF), also called size exclusion Charge Ion exchange chromatography (IEX) Hydrophobicity Hydrophobic i nteraction chromatography (HIC) Reversed phase chromatography (RPC) Biorecognition (ligand specificity) Affinity chromatography (AC) Gel filtration Hydrophobic interaction Ion exchange Affinity Reversed phase Fig. 1

Size exclusion chromatography (SEC) or gel filtration is used to separate a wide range of molecules according to size, including proteins (enzymes), polysaccharides and nucleic acids. There are two major categories of SEC; Group separation and Fractionation. In group separation, for example desalting, samples are separated into two major groups Gel permeation chromatography (GPC) is a type of size exclusion chromatography (SEC). Typically, when an aqueous solution is used to transport the sample through the column, the technique is known. Size exclusion chromatography (SEC) is also known as gel filtration, gel permeation, or sieve chromatography. In addition to separating proteins with different molecules sizes, SEC can be used to resolve oligomeric forms of a particular protein Gel permeation chromatography is a form of size exclusion chromatography in which we use an organic solvent as the mobile phase. Therefore, we can use solutions such as hexane and toluene for this purpose. The stationary phase is a porous material, the same as in gel filtration chromatography

and exclusion chromatography. The gel term generally connotes the use of a nonrigid or semirigid organic gel stationary phase, whereas SEC can pertain to either an organic gel or a rigid inorganic support. Despite this, the term GPC is commonly used interchangeably with SEC. In this chapter w Chromatography is a technique which is meant for separation of a component of a mixture. Similarly, electrophoresis is also meant for separation of components of a given sample. But one needs to understand the difference between chromatography and electrophoresis for analytical needs..
