Does your work involve developing gas-phase monitoring processes? The NOCH-1 spectrometer analyzes gases faster, more easily, and with lower maintenance than traditional techniques like Gas Chromatography (GC). Our gas phase process Raman spectrometer accurately identifies and quantifies gases with excellent sensitivity, but without the hassle or price tag associated with alternative methods. Combined with our flexible software, the GasRaman NOCH-1 spectrometer is an ideal system for process development.

Product Details

The GasRaman NOCH-1 gas phase process Raman analyzer instrument features a diode-pumped solid state (DPSS) laser. The graphic user interface of the control and data acquisition program includes a time trend and ratio calculate in a time chart mode to enable spectral changes with time to be observed.  

The NOCH-1 GasRaman spectroscopy system provides fast and accurate laboratory and online gas phase Raman analysis, with no extractive sampling required.  

Features and Benefits

  • High Rayleigh rejection fiber optic probe

  • Rapid, easy measurements
    • Much faster than Gas Chromatography (GC)
    • No extractive sampling
  • Faster cycling time
  • Less maintenance
  • Accurate identification and quantification
  • Excellent sensitivity
  • Not altered by water vapor  


  • Natural gas
  • Biofuel
  • Methanol from natural gas
  • Combustion monitoring
  • Gasification process monitoring
  • Well-head monitoring for exploration and production
