Rheo-Raman combination

Rheology meets Raman spectroscopy

The Rheometer-Raman Setup (a rheometer connected with a Raman spectrometer) combines two powerful measurement principles: It is the perfect symbiosis of rheology as a mechanical and Raman as a molecular spectroscopy method. The relationship between the macromolecular behavior measured with the rheometer and structural parameters is important for a better understanding of changes in the chemical functionality and microstructure of various materials and their influence on processing and applications.

Key Features

Exploit the full synergy potential of an MCR rheometer combined with a Raman spectrometer

The rheometer and the Raman spectrometer are connected via a fiber-optic Raman probe. This allows flexible positioning of the spectrometer to save space on the laboratory bench (5 m cable length). The MCR rheometer and the temperature device are fully functional and provide the full range of rheological test types in a temperature range from -20 °C to 300 °C. The Raman probe operates though a quartz glass plate to minimize spectral interferences and to provide efficient filtering, which eliminates the need for a silica background measurement. The positioning of the probe can be adjusted using the included linear table and micrometer screws.

Use the of Raman spectrometer of your choice

The renowned MCR rheometer series can be combined with a spectrometer of Anton Paar’s Cora Raman spectrometer series or with many other (e.g. already purchased) Raman spectrometers and Raman probes. With our expertise in both fields, we can develop, provide, and support customized solutions, depending on your application and requirements.

Enjoy modularity and ease-of-use

The Rheo-Raman combination is only one of several well-established optic tools that can be used together with an MCR rheometer. A minimal setup time is required to use the rheometer in combination with Raman or switch to other accessories. Also the Peltier and electrical temperature devices can be used with other rheo-optic tools, e.g. UV-curing, (fluorescence) microscopy, Small Angle Light Scattering (SALS) and polarized imaging. This allows a time- and cost-effective use of measuring instruments. User-friendly features of the MCR rheometer series like ToolmasterTM and QuickConnect are also part of the package.

Discover a whole range of new applications

The Rheometer-Raman Setup opens up unique opportunities in measuring physical and chemical sample properties simultaneously (same sample, same time, and same measurement conditions). It can provide a deeper understanding of changes in the chemical functionality and microstructure of various materials and their influence on processing and applications. Possible applications are the investigation of crystallization processes, chemical reactions (e.g. curing of an adhesive sample), morphology of polymers, temperature behavior and stabilities of suspensions, structural parameters of biological samples (e.g. biofilms, cell cultures), and many more.
