Designed for Malvern Bohlin rheometers, version 6.40 of this control and analysis software incorporates new features, including more-flexible data analysis setup and automation, and a completely new test type. The new multi-wave test mode involves the application of multiple frequencies for faster testing and is useful for studying rapidly changing systems, such as thermosetting resins or the gelation of foodstuffs. Featuring a new template wizard, set-up and storage of analysis routines is easy, and operators can add multiple analyses to the menus for easy re-use. Fewer than five mouse clicks are needed to perform an analysis. Improved model-fitting facilities allow automation of fitting and result reporting on test completion, a function that can be enhanced by automated determination of the best fit from a user-defined list of rheological models. An advanced simplex algorithm is used to optimize convergence to the best model fit to the data. A complete implementation of Time Temperature Superposition (TTS) analysis is available for application to any selected variable. Calculation of WLF and Arrhenius constants is included in the TTS analysis package, as is calculation of extrapolated viscoelastic properties at any frequency and temperature.
