Industrial PhD Pernille Qwist Reckey presented the first publication of her PhD project at EuPAT 9 in Manchester May 15-16.
EuPAT is the pan-European conference on PAT (Process Analytical Technology), organized by EUFEPS.
In this study Pernille demonstrated how RheoStream® can be calibrated to measure the viscosity flow curve as well as viscoelasticity G’ and G” of a HEC gel.
HEC, hydroxyethyl cellulose is a gelforming polymer often used in pharmaceutical topical formulations.

In this study, RheoStream was used in a laboratory setting, off-line, however the instrument is developed to perform real-time characterization of such viscous liquids in manufacturing, where it can be installed and interfaced with the process control system, allowing for much improved rheology control.
