The Thermo Scientific Rheonaut module is a new compact FTIR module for the Thermo Scientific HAAKE MARS rheometer platform. With the new Rheonaut module, users can understand the cause of rheological properties on a microscopic level: Dynamic rheometry and FTIR spectroscopy can be employed simultaneously to monitor the molecular structure development during the reactive processing of a sample and to detect interactions when used in parallel.
Since infrared spectroscopy is a tool capable of identifying the nature of molecular structures and transformations, the addition of an FTIR spectrometer to a rotational rheometer gives the researcher another level of detail pertaining to the comprehension of rheological applications.
With a rheometer, the steady-state and time-dependent viscoelastic properties of a material can be studied as a function of stress and/or strain. However the viscoelastic properties of a material depend on the structure and especially the structural changes of the material on the molecular level. Infrared spectroscopy is an excellent tool for determining the identity and quantities of molecules in a sample.
Using the Rheonaut, both physical and chemical information can be obtained on a sample at the same time, using one instrument. The result enables a comparison of chemical information with rheological properties. The Rheonaut operates in the mid-infrared spectral range since all fundamental absorption bands of a sample are typically found between 400–4000cm-1 (2.5–25µm). This covers the so-called fingerprint region which is generally accepted as unique for each molecule.
