OEM viscometer improves GPC/SEC sensitivity 

Testa Analytical is now offering its advanced viscometer detector to chromatography manufacturers seeking to upgrade their gel permeation chromatography/size exclusion chromatography (GPC/SEC) systems with cutting-edge technology.

A viscometer integrated into GPC/SEC setups provides crucial insights into the physical structure of macromolecules such as polymers, proteins, and polysaccharides. However, performance can vary widely between devices.

Carlo Dessy, Managing Director of Testa Analytical, explained:

"While multiple viscometers once competed in the GPC/SEC market, today our detector stands alone as the only one optimised by design for seamless integration with any commercially available GPC/SEC system.

“Our viscometer’s unique engineering significantly reduces signal noise, increasing sensitivity by over tenfold compared to other options on the market. This improvement enables reliable detection at lower flow rates, lower analyte concentrations, and lower molecular weights - making routine semi micro-GPC/SEC applications feasible. Additionally, it adapts effortlessly regardless of the number of columns in use, consistently returning to baseline without the breakthrough effect seen in other designs.”

This performance leap positions Testa Analytical’s viscometer as a key tool for manufacturers aiming to meet the highest demands of their clients with superior GPC/SEC analysis capabilities.
