Laser Spectroscopic Motor Exhaust Gas Analyzer

HORIBA ONE Series Introduces New N-Compounds Analyzer

The MEXA-ONE-QL-NX is an analyzer for the direct, simultaneous real-time measurement of the four relevant nitrogen-containing exhaust gas components NO, NO2, N2O and NH3.
The analyzer combines a light source based on the new quantum cascade technology (efficient lasers in the mid-infrared spectral region) with a precisely adjusted dual path cell to measure low concentrations with maximum sensitivity. The detection limit complies with current European legal requirements.
Furthermore, the MEXA-ONE-QL-NX offers wide measuring ranges of up to 5000 ppm (for NO). By using extremely narrowband light sources and measuring under reduced pressure the cross-sensitivity to other exhaust gas components can be drastically minimized.
The complete measuring system - including filtration - is specifically developed for the measurement of NH3 and thus guarantees a very fast NH3 rise time (T10-T90) of less than 5 seconds. 
The MEXA-ONE-QL-NX can be operated as a stand-alone analyzer or integrated into the MEXA-ONE software interface for user-friendly and simplified system operation.

For R&D of advanced NOx after-treatment systems

  • Simultaneous real-time measurement of four nitrogen compounds (NO, NO2, N2O and NH3)
  • Wide dynamic ranges for all components (e.g. NH3: 0.6 ppm to 2000 ppm)
  • Fast response times (T10-T90):
    NO, NO2, N2O: <2 s 
    NH3: <5 s
Segment: Automotive Test Systems
Division: Emission Measurement Systems
Base product
Manufacturing Company: HORIBA, Ltd.

Applications

  • Development of new NOx after-treatment systems, such as urea-SCR, CRTs and LNTs
  • Certification of NH3 emissions according to the latest European legislation for light duty vehicles (WLTP/GTR 15)
  • As an R&D tool for worldwide regulations - certification or reporting of greenhouse gas emissions (EPA) or ammonis (Euro VI)

All advantages at a glance

  • Compliant with WLTP/GTR 15 for NH3 measurement
  • Suitable for the measurement of very low concentrations
  • Wide dynamic ranges (up to 5000 ppm)
  • Very low cross-sensitivity for other exhaust gas components
  • No operating gases other than compressed air
  • Direct NO2 measurement
  • Easy handling (no liquid nitrogen cooling necessary)
  • Operation within HORIBA ONE PLATFORM
