Gel permeation chromatography of asymmetric proteins
Analytical Biochemistry, 1982Abstract The gel permeation chromatographic behavior of three asymmetric proteins—collagen, fibrinogen, and the prolate ellipsoid lysozyme—was investigated using a variety of gel and high-performance liquid chromatographic media of various pore sizes and a wide range of flow rates.

Concentration effect in gel permeation chromatography
Journal of Chromatography A, 1978Abstract The effect of the viscosity of the injected polymer solution in gel permeation chromatography was investigated using samples of polystyrene standards with molecular weights above the exclusion limit of the column packing used. It was confirmed that a relationship existed between the specific viscosity of the injected polymer solution and the

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.

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.

Gel permeation chromatography of polymers
Journal of Polymer Science: Polymer Symposia, 1975AbstractThe literature on gel permeation chromatography (GPC) is surveyed and briefly reviewed to provide a guide to some of the more important references, particularly those dealing with equipment and polymer molecular weight determination. A number of applications of GPC in the authors' laboratories are discussed in order to illustrate use of the GPC

Gel Permeation Chromatography: Gel Preparation and Packing Technique
Nature, 1967SINCE the original publication by Moore1, gel permeation chromatography has been widely recognized as a rapid means of assessing the molecular weight distributions of polymeric materials soluble in organic solvents. While the use of this technique, principally based on the reliable commercial instrument2, is well established, reference in published ...
