Instrument Capabilities
The Bruker INVENIO-R is a research-grade Fourier Transform Infrared (FTIR) spectrometer for chemical and materials characterization. The system provides broad spectral coverage from the near-infrared through the mid- and far-infrared regions and is equipped with multiple detector options, including DTGS and a liquid-nitrogen-cooled MCT detector. It supports transmission, reflectance, and accessory-based measurements for materials including polymers, thin films, coatings, composites, and other organic and inorganic materials. Rapid-scan capabilities enable time-resolved measurements, while external triggering and macro-development capabilities support integration with automated and electrochemical experiments. The system also includes OPUS and OPUS/3D software for spectral acquisition, analysis, and visualization. The system is currently designed to also operate inside a glovebox which makes it ideal for studying air-sensitive samples.
Key features:
- Mid-IR: approximately 11,000–380 cm⁻¹ with the KBr broadband beamsplitter.
- Far-IR (FIR): 680–30 cm⁻¹ using the multilayer beamsplitter and FIR detector configuration
