Malvern will present the results of a collaborative study on the applicability of high-frequency optical and mechanical rheometry on gels and stiff samples at the Pacific Rim Conference on Rheology.
The study, entitled 'High Frequency Rheology of Entangled and Network Forming Polymers', will be presented as part of the Non-Newtonian Fluid Mechanics and Micro Fluidics symposium on the second day of the event, which runs from 1-6 August 2010 in Hokkaido, Japan.
Samiul Amin and Torsten Remmler, rheology specialists at Malvern Instruments, are two of the contributors to the study.
The relaxation mechanisms in complex fluids such as polymeric solutions, can affect the material's dynamics over a range of timescales.
The application of traditional rheometry techniques across extended dynamic ranges is limited at the high-frequency (short timescale) end owing to instrument constraints.
Despite new developments in both optical and mechanical high-frequency devices, the applicability of such techniques in the study of gels or very stiff samples in particular is poorly understood.
The study aims to fill this knowledge gap.
Those interested in investigating the latest measurement technology can visit the Malvern Instruments exhibition stand and can try out rheometers such as the Kinexus.
