Shimadzu EDX-8100 Energy Dispersive X-ray Fluorescence

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.

The integrated multi-detector module (RI, LALS, RALS, UV, DP, IP) together with the OMNISEC software is used to the characterization of macromolecular compounds such as synthetic and natural polymers or proteins.


  • Multi-detector module (RI, LALS, RALS, UV, DP, IP)
  • A wide range of columns for analytical GPC/SEC of synthetic and natural polymers and proteins


  • No detectors in a parallel flow path meaning higher sensitivity and better quality results
  • Complete advanced GPC / SEC system with triple or quad detection for molecular weight determination and mass distribution
  • Static light scattering. Absolute molecular weight by RALS (Right Angle Light Scattering) / LALS (Low Angle Light Scattering) as an alternative to MALS
  • Viscometric detector for the determination of the intrinsic viscosity and providing information about the structure of the sample (e.g. about the branching of the polymer)

Application area:

  • Polymers industry
  • Pharmaceutical industry
  • Cosmetics industry
  • Polymers industry


Exemplary applications:

  • OMNISEC is a powerful tool for taking control of the performance, quality and value of your product, whether that’s a synthetic polymer in industry, a natural polymer or polysaccharide used in food or pharmaceutical products, or a protein or antibody used in biopharmaceuticals.
  • Measurements degradation of the materials for example polymers, drugs
  • Assess and predict activity by measuring molecular weight
