With 30 years of chromatography and light scattering experience, the Viscotek GPC/SEC systems and detectors from Malvern provide solutions for all applications of proteins, synthetic and natural polymers.
Complete systems are available as out-of-the-box solutions for macromolecular characterization. Alternatively, upgrade an existing system through the addition of a modular detector.
The entire Viscotek range is backed by the Malvern’s global support and training network.

Using a light scattering detector as part of a multi-detector Size Exclusion Chromatography system provides the accurate molecular weight (MW) data needed to assess the activity, safety and clinical efficacy of therapeutic proteins.
The second virial coefficient of Human Serum Albumin (HSA) was measured using a SEC-MALS 20 detector connected to a Refractive Index concentration detector and an online differential viscometer. Two different buffer conditions, Phosphate buffer pH 7....
This poster shows how Rheometry and GPC can be complementary tools for characterizing the behaviour of polysaccharides in solution
This poster describes the use of flow injection polymer analysis (FIPA) as an analytical tool for xylene soluble (XS) determination with quick and easy simultaneous measurements of molecular weight (MW), intrinsic viscosity (IV) and XS%. The techniqu...
In this paper we will review and present some of the old and new issues and practical solutions to implementing reliable, robust absolute molecular weight and structural determinations in HT-GPC of polyethylene.
