OMNISEC

Malvern Panalytical's OMNISEC is a Gel Permeation Chromatography (GPC) / Size Exclusion Chromatography (SEC) system for the measurement of absolute molecular weight, molecular size, intrinsic viscosity, branching and other parameters. It includes OMNISEC RESOLVE, the integrated GPC/SEC module, OMNISEC REVEAL, the integrated multi-detector module and OMNISEC software for the characterization of synthetic and natural polymers, and proteins. The SEC-MALS detector complements RALS/LALS or can be used as the sole light scattering detector.

The OMNISEC system reached end of manufacture in May 2025.
