New control and analysis software for Malvern Bohlin rheometers
New control and analysis software for Malvern Bohlin rheometers
Keywords: Rheology, Instruments, Software
Malvern Instruments has launched a new software version for its range of Malvern Bohlin rheometers (Plate 1). Version 6.40 incorporates many significant 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 especially useful for studying rapidly changing systems such as thermosetting resins or the gelation of foodstuffs.

New software version for Malvern Bohlin rheometers
A number of new analysis routines have been built into the software, including a new template wizard, improved model fitting capabilities, Time Temperature Superposition (TTS) analysis, and new data manipulation routines. The software also features extended language support with English, French, German and Spanish language versions available as standard, and the capacity for reconfiguration to support most major European languages.
With the 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.
Additionally, an automated peak and valley determination wizard for any variable is included in the standard package together with statistical analysis of data sets. Multiple data smoothing methods are also available, including Floating mean average, Savitsky Golay. Polynomial and Fast Fourier transform.
