The efficiency of gel permeation chromatography

Journal of Polymer Science Part C: Polymer Symposia, 1968
AbstractThe resolution power of gel permeation chromatography (GPC) columns and their combinations is tested as a function of the pore sizes of the gels and as a function of the elution velocity. The efficiency of GPC is characterized by the ratio UG/UT, where UG is the experimental, and UT the theoretical, inhomogeneity.

Gel Permeation Chromatography of Insulin

Journal of Liquid Chromatography, 1980
Abstract Aquas gel permeation chromatography of insulin under denaturating conditions has been successfully performed on three different chromatographic supports. The separation pattern was identical to that obtained on soft gels (Sephadex, BioGel). The elution time was 10-20 min, recovery 98-100%.

Review of gel permeation chromatography

British Polymer Journal, 1971
AbstractGel permeation chromatography (g.p.c.) with organic solvents is of immense value in the characterisation of plastics and resins. Topics reviewed here are column packings and packing techniques, instrumental features, theories of the separating process and of instrumental dispersion, the use of g.p.c.
