Size-exclusion chromatography of high molecular weight water-soluble polymers

A preparative‐scale, aqueous size‐exclusion chromatography system was constructed for fractionation of large molecular weight polymers. Calibration of molecular weight to elution volume was accomplished without polymer standards by using an eluent viscosity detector in series with a refractometer. T...

Zusammenfassung:	A preparative‐scale, aqueous size‐exclusion chromatography system was constructed for fractionation of large molecular weight polymers. Calibration of molecular weight to elution volume was accomplished without polymer standards by using an eluent viscosity detector in series with a refractometer. The system was found to have a hydrodynamic size‐separation resolution that ranged from 500 to 3500 Å.
