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
