Field of application
The Raman Rxn4 analyzer powered by Kaiser Raman technology is the optimal choice for manufacturing or process environments. Raman Rxn4 provides high-resolution performance for in situ, real-time measurement and control. It features unique self-monitoring, diagnostics, and self-calibration to ensure the validity of each measurement. Stackable in a standard 19" rack, the Raman Rxn4 saves valuable space on the production floor. It is also offered with an optional stainless steel NEMA 4X enclosure.
Chemical: reaction monitoring, blending, catalysis investigations
Polymer: polymerization reaction monitoring, extrusion monitoring, polymer blending
Pharmaceutical: API reaction monitoring, crystallization, polymorph
Biopharmaceutical: bioprocess monitoring and control, PAT/QbD applications, cell culture, fermentation, downstream operations, cGLP/cGMP compatible
