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
Borealis monitoroi polypropeeni- ja polyeteenitasoja olefiinin polymerointireaktioiden aikana kemianteollisuuden jatkuvasti syötettävissä silmukkareaktoreissa.
Probe spectral coverage is limited by the coverage of the analyzer being used.
