Description

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.

Field of application
  • 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
  • Suitable for hazardous/classified environments
