- Uncover the molecular origins of viscoelastic behavior
- Gain deeper understanding of material properties
- Obtain scientific proof for observed rheological effects
- Reduce development cycles via a more targeted approach
- Efficient root cause analysis and corrective actions in case of deviations
The Rheo-Raman setup – an MCR rheometer integrated with a Cora 5001 Raman spectrometer – combines two powerful measurement principles: the mechanical insights of rheology and the molecular specificity of Raman spectroscopy. By linking rheological behavior with structural parameters from Raman spectra, academic researchers can uncover the molecular origins of viscoelastic properties – replacing hypotheses with proof and enabling publication of papers in high-impact journals. In industry, the Rheo-Raman system supports efficiency gains by reducing trial-and-error cycles, identifying deviations, pinpointing their root causes, and enabling precise corrective actions.
Key features
Reduce your time-to-market with fewer development cycles
In polymer and resin product development, desired properties are often achieved via experience combined with time-consuming iterative trial and error processes. By adding chemical insights to physical measurements through the Rheo-Raman approach, development teams gain a clear picture of what drives material performance. This enables more targeted optimization, reduces the number of development cycles, saves costs, and shortens time-to-market.
Boost your research results for the next higher-grade publication
In academic research, rheological measurements alone often lead to observational results without a clear molecular explanation. By combining rheological results with chemical and molecular insights, researchers gain scientific proof – not just hypotheses.
This deeper understanding supports publication in higher-grade journals, increases visibility at top conferences, and strengthens applications for research funding – fueling a continuous cycle of scientific advancement.
Key application areas are: material science, polymer science, resins, glues and adhesives, including photo polymerization, for which simultaneous UV exposure and Raman offer strong advantages.
Optimize your polymer production processes
Developing new polymer production processes, including the right parameters, often involves repeated iterations that consume time and capacity. The valuable information acquired through a combination of physical measurements and chemical insights using the Rheo-Raman setup makes defining process windows more focused and efficient. This approach helps minimize trial and error, accelerates process refinement, reduces costs, and brings products to market faster.
Benefit from the Rheo-Raman system – or use the instruments separately
Due to cumbersome integration and alignment procedures that require specialized skills, similar systems on the market can only be used in combination. In contrast, the Rheo-Raman setup with MCR Evolution and Cora 5001 can be assembled or disassembled by users in just a minute. A visit from a service technician is not required. You can use the rheometer and Raman analyzer separately or combine them, depending on your measurement needs. This means you’re getting three solutions in one – from one and the same supplier. We guarantee that both the individual and combined solutions will work seamlessly together.
More effective QC with root cause analysis down to molecular origins
In industrial QC of polymer products such as polymer melts, adhesives, and resins, resolving deviations is often a slow, trial-and-error process based on observations and user experience. Offline testing adds further delays and unnecessary costs, while quality issues remain unresolved.
By combining rheology with Raman spectroscopy, users gain real-time, in situ chemical insights directly in the rheometer. This enables immediate identification of chemical/molecular root causes and allows for fast, targeted corrective action – reducing costs, avoiding liability risks, and keeping processes on track.
