Product catalog summary
Functional Principle
Raman spectroscopy is a technique for chemical analysis of solid, liquid, or gaseous samples. It uses inelastic scattering of monochromatic laser light, known as Raman scattering. This interaction with molecular vibrations results in a shift in the energy of the laser photons, providing information about the sample's nature.
Differentiation to Mid-IR
Raman spectroscopy combines advantages of both Mid-IR and Near-IR spectroscopy. Like Mid-IR, it observes fundamental molecular vibrations, linking Raman spectral features to molecular functional groups. Unlike Mid-IR, Raman can use robust optics like fused silica and sapphire, common in Near-IR and UV-Visible regions.
Raman Probes
These are designed for Raman measurements of liquids in process and lab applications. They offer benefits such as adaptability for specific application requirements, with options in size, material, optics, connectors, excitation wavelength, and filters. Fields of application include process & PAT, chemical, pharmaceutical, forensics, petrochemical, and life sciences.
TIDUS RAMAN IMMERSION PROBE
Suitable for laboratory and process sampling, this fiber-optically coupled probe has a modular construction for maximizing sample opportunities. It allows non-contact optics for measurements through windows or at a distance, with process optics providing a laser safety interlock.
RFP-500 PROCESS RAMAN PROBES
These robust probes are designed for demanding applications, combining durable optical designs with Hellma Axiom’s proprietary welded metal window sealing technique.

Raman Probes … FOR RAMAN MEASUREMENTS OF LIQUIDS IN PROCESS AND LAB APPLICATIONS Functional Principle Raman spectroscopy is a spectroscopic technique used for chemical analysis of solid, liquid or gaseous samples. It relies on inelastic scattering, or Raman scattering, of monochromatic laser light. The laser light interacts with molecular vibrations, resulting in the energy of the laser photons being shifted up or down. The shift gives information about the nature of the analysed samples. Differentiation to Mid-IR Raman spectroscopy blends some of the advantages of both Mid-IR and Near-IR spectroscopy. As in the case of Mid-IR, the molecular bands observable by means of Raman scattering correspond to fundamental molecular vibrations, providing a one-to-one correspondence between Raman spectral features and molecular functional groups. Raman has a major advantage over Mid-IR in that it can employ the robust fused silica and sapphire optics commonly used in the Near-IR and UV-Visible regions. Advantages and benefits: Ideal for Instrument manufacturers (OEM), as it can be adapted to specific application requirements. Options include: // Size and material // Optics and connectors // Excitation wavelength and filters Multipass Spectrum of Methane Fields of application: // Process & PAT // Chemical // Pharmaceutical // Forensics // Petrochemical // Life Science
