The OmniSEC GPC/SEC platform brings ground-breaking performance to the analysis of polymers, proteins.

GPC/SEC is a two-step analytical process that involves separating a sample on the basis of its size and then analyzing the resulting fractions. The technique delivers molecular weight, molecular size and structural information, all of which define the performance of many industrially important materials. Coupling the efficient sample separation of OMNISEC RESOLVE with the fully optimized, multi-detector, information-rich analysis delivered by OMNISEC REVEAL,

OMNISEC REVEAL includes the following four detectors: refractive index, UV/Vis Photodiode array, low angle/right angle light scattering and viscometer. Its light scattering detector is the most sensitive on the market meaning it can accurately measure molecular weights as low as 200 Da or injection masses of 100 ng. A new self-balancing viscometer design with a user exchangeable capillary bridge boosts instrument productivity and cuts lifetime costs by extending viscometer life, reducing instrument downtime and minimizing maintenance requirements.

OMNISEC RESOLVE consists of a sample degasser, pump, autosampler and column oven, each optimized for precise, high resolution separations. This translates into smooth stable baselines for detector analysis, which in turn boost the accuracy of all measurements. Key features here include a low volume, high efficiency degasser design that enables rapid switchover from one sample type to another, thereby delivering substantial timesaving in busy multi-user labs. The new temperature controlled autosampler eliminates injection waste, minimizing the sample required for routine measurement, and in combination with the column oven maintains all samples under closely controlled conditions throughout the analysis. This is especially important when dealing with materials such as proteins which can be temperature sensitive.
