Theory behind chromatography

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 ... WebbThe theory was integrated into the chromatography technique in 1941 by Martin and Synge. According to the model, the chromatographic column consists of separate layers known as the theoretical plates. These plates are hypothetical zones or stages that help in establishing an equilibrium between two phases.
