Infrared spectroscopy is an excellent tool for determining the identity and quantities of molecules in a sample. Rheology, however, as many other analytical techniques that measure the physical properties of a sample provides little or no chemical information. As a result, many separate physical and chemical measurements may be necessary to fully characterize a sample. Using the RHEONAUT both, physical and chemical information can be obtained on a sample at the same time using one instrument. For example, transient molecular structures can be detected, allowing for tracking compositional changes in curing reactions or molecular orientations of polymer melts. In other words, the chemistry of a sample in a shear field can be studied in situ using FTIR spectroscopy. The result enables a comparison of chemical information and rheological properties.

The RHEONAUT operates in the mid-infrared spectral range since all fundamental absorption bands of a sample are typically found between 400 – 4000 cm-1 (2,5 – 25 µm). Thus, the RHEONAUT well covers the so-called “fingerprint region” which is generally accepted as unique for each molecule.


About the Thermo HAAKE MARS Rheometer

The Thermo HAAKE MARS is one of the most modular high-end rheometer platforms in its class. The innovative HAAKE MARS system was designed for flexibility and meets the most demanding requirements in research and development with an architecture that permits integration of custom modules. The concept is designed to meet today's and future rheology needs while protecting prior accessory investments. A variety of specialized and application-oriented measuring cells are available, e.g. for food, construction materials or UV-curing materials. Thus the name “MARS” reflects more than ever the philosophy of the product: Modular Advanced Rheometer System.
