New pages on the Malvern Instruments website provide information that enables scientists to make informed choices about detector configurations for their specific GPC/SEC applications. Showcasing the company’s comprehensive range of Viscotek systems and detectors for gel permeation/size exclusion chromatography (GPC/SEC) these pages help analysts to identify high productivity configurations for polymer, macromolecule and protein applications. Malvern’s product range includes high sensitivity refractive index (RI), UV, dynamic and static light scattering detectors, and a viscometer, all of which are available as part of a complete Viscotek GPC/SEC system, or as individual modules offering exceptional flexibility to those with existing chromatography systems.

GPC/SEC is a central analytical technique for the analysis of proteins, polymers and macromolecules because of its ability to measure defining characteristics such as molecular weight, molecular weight distribution and molecular size. Modern GPC/SEC systems typically incorporate multiple detectors that work together to deliver information about the physical and structural features of the sample, enabling detailed investigation of, for example, polymer branching or the aggregation behavior of proteins.

The Viscotek range of detectors includes refractive index (RI) and UV technology for concentration measurement. A viscometer enables universal calibration, eliminating the need for relevant calibration standards, or, when used with a light scattering detector supplies structural insight Malvern offers both a low angle light scattering (LALS) detector and a dynamic light scattering detector (Zetasizer µV), either of which can be used to directly measure molecular weight and/or molecular size.

By offering detectors individually and making each compatible with every make of GPC/SEC system Malvern Instruments provides the analyst with the flexibility to tailor a detector array to maximize information flow and experimental productivity for their specific application.

Size Exclusion ChromatographySize exclusion chromatography (SEC) is a liquid chromatographic technique used to separate and identify molecules based on their size, including polymers, proteins, nanoparticles & nucleic acid. SEC is further subdivided into gel filtration chromatography (GFC) and gel permeation chromatography (GPC) when an aqueous or organic mobile phase is used respectively. HPLC-based SEC systems and columns are available for analytical separation alongside SEC spin columns or filters to prep samples for many protocols.

It is widely used in fields like biochemistry, pharmaceuticals, and environmental analysis. By exploiting differences in the interaction of substances with a stationary phase and a mobile phase, chromatography enables precise purification and quantification of compounds. Whether you're working with complex biological samples or industrial chemicals, chromatography is essential for obtaining high-quality results.
