OMNISEC

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.

As a research tool, it accelerates research into these molecules by providing absolute information for a wide range of applications making it an ideal tool for universities. It reduces service expense and downtime and increases productivity with easy-to-use intuitive software.

Market leading high sensitive light scattering

• Measure low molecular weight samples with greater accuracy (down to 200 g/mol)

• Measure lower sample concentrations (newly synthesized polymers and proteins)

• Measure low dn/dc samples with greater accuracy and sensitivity 

High sensitivity Refractive index 

• Greater accuracy and less subjectivity at lower concentrations

• Measure lower concentraions of highly viscous materials to prevent column overload

Integrated robust differential viscometer 

• Measure Iv of samples to determine structure and branching 

• Robust to all GPC solvents and a wide pH range broadening available applications 

Mechanical viscometer bridge autobalance

• Improved viscometer data quality and accuracy

Fully integrated detector module 

• Better temperature control and reduced interdetecor volume = better chromatography 

• Improved separation quality and resolution

All detectors in series 

• no detectors in a parallel flow path meaning higher sensitivity and better quality results

Work flow orientated software

• Makes GPC/SEC measurements and analysis easy and intuitive

How it works

In size-exclusion chromatography, molecules are separated according to their hydrodynamic radius as they enter and exit the pores of a porous gel packing matrix in the column. Like other HPLC-based techniques, this involves the use of a pump, column and at least one detector to measure the sample as it elutes. An OMNISEC GPC/SEC system includes the following components:

Degasser

• Rapid mobile-phase exchange thanks to low volume degasser

Pump

• Rapid mobile-phase exchange thanks to self-priming pump

• Reduced service requirement thanks to novel continuous back seal flushing mechanism

Autosampler

• Protect samples from aggregation with autosampler temperature control

• Use your preferred sample format; vials or 96-well microtiter plates

• Reduce sample use with zero-waste mode

Column Oven

• Temperature control of up to 6 analytical columns

Refractive Index

• Measure the concentration of any solute with excellent sensitivity

UV/Vis PDA

• Measure absorbance at any wavelength from 190-900 nm

• Assess changes in absorbance spectra

• Characterize copolymers

Light Scattering

• Measure absolute molecular weight in a wider range of applications

• Measure as little as 100 ng of material

• Measure molecular weights down to 200 Da

Viscometer

• Better intrinsic viscosity measurements thanks to automated balancing

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