It is found that the "retention volume" in gas adsorption chromatography may be identified in a very simple way with the concept of "apparent volume" in the equation of state for high temperature physical adsorption first derived by Halsey etal.

Thiophilic Adsorption Chromatography
2003Thiophilic adsorption is useful for the purification of immunoglobulins under mild conditions (e.g., see ref. 1). Although there are several established procedures for the purification of immunoglobulins (2-5), thiophilic adsorption appears thus far to be unique in its capacity to adsorb three major classes of immunoglobulins (and their subclasses) (6 ...

Expanded‐Bed Adsorption Chromatography
Current Protocols in Protein Science, 2005AbstractExpanded‐bed adsorption (EBA) chromatography is a convenient and effective technique for the capture of proteins directly from unclarified crude sample. In EBA chromatography, the settled bed is first expanded by upward flow of equilibration buffer.

Liquid Chromatography and Adsorption
2015Liquid chromatography and adsorption processes are based on the differential affinity of various soluble molecules for specific types of solids. In these processes, equilibrium is approached between a solid phase, often called the resin, or stationary phase, and the soluble molecules in a liquid phase.

Adsorption models in chiral chromatography
Journal of Chromatography A, 2012The review delivers the analysis of the literature data on adsorption equilibrium in chiral systems. Chiral adsorbents usually comprise several groups of nonselective and enantioselective active sites. Each group may be heterogeneous in itself. A dynamic equilibrium between different conformations of chiral selectors, nonstoichiometric adsorption, and ...

On the selectivity of adsorption chromatography
Journal of Applied Polymer Science, 1996In this paper, the shape of chromatograms obtained by elution of copolymers with a mixture of solvent-nonsolvent of variable composition has been studied from a theoretical point of view. It is assumed that the thermodynamic quality of the mixture at which the copolymer is eluted depends only on its composition and not on its mass and structure. If one

Adsorption chromatography on cellulose
Journal of Chromatography A, 1987Abstract The adsorption on cellulose of a wide range of organic compounds from aqueous ammonium sulphate solutions was studied. The adsorption increased with increasing concentration of ammonium sulphate for all the compounds examined, and plots of their RM values against the logarithm of the activity of ammonium sulphate gave essentially parallel ...

Measurement of adsorption isotherms by liquid chromatography
Journal of Chromatography A, 1984Adsorption behavior on silica-bound hydrocarbonaceous sorbents used in high-performance liquid chromatography was investigated by frontal chromatography and elution on a plateau, and procedures were developed for data collection, analysis and correlation. Isotherms of selected compounds were measured, including several of biological relevance.

Adsorption chromatography of phenylalanine peptides on Sephadex
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1968The adsorption properties of dextran gels have been utilized to separate the first six members of an homologous series of phenylalanine peptides, the longer members being more highly retarded. Separation is influenced by gel structure, pH and the ionic environment.

Removal of plasma cholesterol by adsorption chromatography
Atherosclerosis, 1975Batch and column chromatography with porous glass decreased the plasma concentration of cholesterol. Extracorporeal circulation of blood through a column filled with porous glass, as well as exchange transfusion with blood made hypocholesterolemic by passage of its plasma through a column filled with porous glass, temporarily reduced plasma cholesterol
