Catalysis Research
In-situ catalyst characterization and reaction monitoring with DRIFTS technology for heterogeneous catalysis research.
Catalysis research demands real-time insights into catalyst behavior under actual reaction conditions. Our advanced DRIFTS (Diffuse Reflectance Infrared Fourier Transform Spectroscopy) solutions combine the Specac Praying Mantis accessory with Bruker INVENIO FT-IR spectrometers to provide unparalleled sensitivity and environmental control for studying heterogeneous catalysts, surface chemistry, and reaction mechanisms.
