Kaiser Raman Rxn2 analyzer

The bridge from laboratory analysis to the process environment

The Kaiser Raman Rxn2 analyzer adeptly harnesses the power of Raman spectroscopy while serving as an ideal bridge from lab-to-process. Designed for use in analytical laboratories with model transfer capabilities, the Raman Rxn2 is heavily relied on for routine sample identification, support of R&D projects, early process development, and scale-up settings for in situ analysis.

Combined with our high-performance sampling probes, the Raman Rxn2 delivers high resolution performance for real-time, in-process measurement and control. It features unique self-monitoring, diagnostics, and self-calibration to ensure the validity of each measurement. Available as a benchtop or on a mobile wheeled cart, the Raman Rxn2 offers location convenience and portability for process development laboratories.
