Gel matrices for scanning gel chromatography
Biophysical Chemistry, 1979I have examined the light-scattering behavior of a number of gel matrices used in gel filtration chromatography. The angular dependence of light scattering by Sephadexes is consistent with treatment of the particles as large scattering particles with a low refractive index increment (mu).

Gel chromatography of carbohydrates on polysaccharide gel
Journal of Polymer Science: Polymer Symposia, 1980AbstractLiquid chromatographies of high and low‐molecular carbohydrates and polyethyleneglycols of different molecular masses were studied on porous microspherical cellulose. Dependence of the distribution coefficients of polymer molecules on molecular mass was determined.

Fluorinated gels for gel permeation chromatography
Die Makromolekulare Chemie, 1993AbstractThe aim of these investigations was the development of stationary phases for GPC compatible with fluorinated solvents. The properties of crosslinked copolymers of 4‐(2‐heptafluoropropoxy‐1, 2,2‐trifluoroethoxy)styrene (1) were investigated in dependence of the mode of synthesis. Divinylbenzene (DVB) was used as crosslinking agent.

Principles of gel chromatography
Journal of Chromatography A, 1970Abstract The principles of gel chromatography have been examined with regard to general chromatographic theory. It is shown that the elution volume for a solute is solely determined by the partition of a solute between the mobile and stationary phases and that various forms of diffusion only contribute to the width of the peak eluted.

Gel diffusion chromatography of dextran
Journal of Chromatography A, 1962Abstract Glucose and dextrans of molecular weight 5,000 to 300,000 can be partially separated chromatographically on columns of agar (6–9 %) with buffer (pH 8.0) or water as eluant. Agarose gels (4 %) can also be used with water as eluant. The method can be used to estimate approximately the molecular weight distribution in small samples of clinical ...

Separation Science, 1971
Abstract The technique of gel filtration chromatography is described, with a guide to relevant literature on methods, theory, and applications, especially the use of GFC in analysis of molecular interactions, both macromolecular and small molecule-macromolecule aggregation.

Endeavour, 1984
Abstract Gel permeation chromatography is the most valuable single technique in the molecular weight characterisation of polymers. The power of this technique lies in its ability to give information on the whole molecular weight distribution. In Britain, the Polymer Supply and Characterisation Centre provides a GPC service for research workers in the

Gel Permeation Chromatography of Heparins
Thrombosis and Haemostasis, 1980SummaryGel permeation chromatography of heparins using water as solvent has recently been used to obtain fractions for biological investigation. We find that heparin fractions obtained in this way are not, necessarily, differentiated simply on a molecular size basis as has been alleged.

Journal of Chromatography A, 1976
Abstract An automated gel permeation chromatograph-low-angle laser light-scattering system capable of measuring the molecular-weight distribution of soluble polymers without the necessity of calibration is described. The automation system eliminates most of the tediousness associated with molecular-weight distribution measurement.
