Malvern Panalytical - Chromatography & Mass Spectrometry - OMNISEC

The world's most advanced multi-detector GPC / SEC system

Malvern’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.

  • Molecules are separated by their hydrodynamic radius  

  • Better intrinsic viscosity measurements thanks to automated balancing  

  • Reduced service cost and time thanks to user-exchangeable capillaries  

  • Measure as little as 100 ng of material and molecular weights down to 200 Da 

OMNISEC: sensitive & accurate characterization of polymers & proteins

Malvern’s OMNISEC is a complete gel permeation/size exclusion chromatography (GPC/SEC) solution for the advanced characterization of synthetic and natural polymers, and proteins. This integrated GPC/SEC platform is made up of 3 components - OMNISEC RESOLVE, an integrated pump, degasser, autosampler and column oven; OMNISEC REVEAL, an integrated multi-detector; and OMNISEC software. This video describes the main features of OMNISEC and the benefits they bring to customers seeking the highest level of sensitivity and accuracy in their measurements of macromolecules.
