Request InfoTesta Analytical Solutions eKThe AYE Combo gel permeation chromatography (GPC) and size exclusion chromatography (SEC) detector from Testa Analytical Solutions eK has a high-performance refractometer as an integral part of a viscometer, allowing both concentration and viscosity to be measured simultaneously on the same sample segment. As a consequence, the refractometer/viscometer detector enables a more accurate determination of molecular parameters and is particular suitable for applications focused on determining the structure and branching of complex polymers.
