Versatile GPC/SEC viscometer

Testa Analytical’s high-performance viscometer is engineered to integrate seamlessly with any commercially available GPC/SEC system, offering researchers a flexible, high-sensitivity solution for polymer and protein analysis.

Viscometry remains a key technique for gaining structural insight into macromolecules in gel permeation chromatography (GPC) and size exclusion chromatography (SEC). Unlike conventional detectors, Testa Analytical’s viscometer has been specifically designed to overcome the limitations often encountered with traditional systems.

“While the GPC/SEC market once had several viscometer options, today ours is the only one that can be design-optimised to work with any existing system,” said Carlo Dessy, Managing Director of Testa Analytical.

Thanks to its unique architecture, the detector achieves ultra-low signal noise, resulting in a more than tenfold increase in sensitivity compared to other commercial viscometers. This makes it ideal for low-concentration or low-molecular-weight samples - including polymers, proteins, and polysaccharides - and enables reliable performance even at lower flow rates or in semi-micro GPC/SEC setups.

Another advantage lies in its baseline stability. The viscometer returns to baseline automatically without the breakthrough effect that often affects other models, regardless of how many columns are used in the system - eliminating the need for further adaptation.

For labs seeking robust performance and broad system compatibility, Testa Analytical’s viscometer offers a proven, flexible solution to enhance the accuracy and efficiency of macromolecular analysis.
