E-Z-Raman® On-line Raman Analyzer


AppliTek has adopted Raman spectrometry as a powerful tool analyzing a large set of critical parameters in liquids or powders. Raman spectrometry is based on Raman scattering of atoms or molecules, which is directly related to the chemical properties of the sample or sample components.

What are the main advantages of using Raman spectrometry for process applications?
  • No sample pretreatment required for samples containing water
  • No additional chemicals required
  • Short analysis times. Typically 30 s to 3 minutes (GC ~ 11 to 15 minutes)
  • Excellent spectral resolution
  • Remote analysis via fiber-optics (> 200 meters of fibers)
  • Use directly in-line
  • Multiplex capabilities (up to 18 channels/streams)

 The concept design of the E-Z-Raman® On-line Raman Analyzer, including advanced optics and a powerful laser with a high life-time, clearly outperforms comparable analyzer systems with much higher signal losses. On top of that, AppliTek takes care of the complete solution from feasibility to calibration to commissioning.
