Optical spectroscopy is a crucial technology in today's context for real-time process monitoring and optimization. Fiber-coupled probes enable immediate observation of the process without any time delay. The MATRIX-F II FT-NIR spectrometer allows direct measurements in process reactors and pipelines, leading to a better understanding and control of the process. Its innovative technology provides consistent high quality results, less downtime and direct method transfer. All Bruker process spectrometers are characterized by robustness, long-term stability, and low maintenance costs.
