WebbSize exclusion chromatography (SEC) separates molecules based on their size by filtration through a gel. The gel consists of spherical beads containing pores of a specific size distribution. Separation occurs when molecules of different sizes are included or excluded from the pores within the matrix. WebbHistory of Supercritical Fluid Chromatography In 1822, French physicist Charles Cagniard de la Tour put a liquid and a flint ball into a Papin pressure vessel constructed using a rifle and heated the liquid in a sealed cannon. He then conducted an experiment to determine whether a product was produced.
WebbHydrophobic Interaction Chromatography: Uncovering the Underlying Theories There are three major theories that may help explain the mechanism behind HIC – (1) the salting out theory, (2) the thermodynamic theory and (3) the surface tension or Van der Waals forces theory. Salting Out Theory WebbGel filtration (GF) chromatography separates proteins solely on the basis of molecular size. Separation is achieved using a porous ... matrix. Hence, proteins are eluted from the GF column in decreasing order of size. This unit describes the experimental theory behind gel filtration and contains many useful tables listing the properties and ...
