Field of application
The Raman Rxn-40 probe is a sealed immersion probe for in situ Raman spectroscopy of liquid-phase samples in a laboratory or process plant setting. The process connection for the Raman Rxn-40 can be swaged, compression-mounted, flange-mounted, or installed in an Endress+Hauser flow cell, and is NeSSI compatible. These versatile options allow for direct insertion in slip-streams, drain-values, reactors, circulation loops, blend headers, and inlet or outlet pipework.
Chemical: reaction monitoring, blending, catalysis, feed and final product monitoring
Polymer: polymerization reaction monitoring, extrusion monitoring, polymer blending
Oil & Gas: fuel blending, fuel characterization
Pharmaceutical: API reaction monitoring, crystallization, polymorph, blending
Benefits
Customizable to your process
Robust design with a range of process connections
In situ/no transfer lines or fast-loops required
Faster, simpler installation
Support for a range of chemical processes and corrosivity requirements
Ensures safety and meets regulatory requirements
