- Model MEXA-ONE-QL-NX - Laser Spectroscopic Motor Exhaust Gas Analyzer



HORIBA ONE Series Introduces New N-Compounds Analyzer. High accurate nitrogen compounds measurement system using QCL-IR method newly employs 'HORIBA ONE PLATFORM'. This system provides the usability and expandability for your test laboratories, as well as other HORIBA ONE series instruments.

  • Simultaneous real-time measurement of four nitrogen compounds (NO, NO2, N2O and NH3)
  • Using Quantum Cascade Laser Mid-infrared Spectroscopy
  • Wide dynamic range (e.g. NH3: 0.6 ppm to 2000 ppm)
  • Fast response measurement with the analyzer installed
    near the engine*1
    NO / NO2 / N2O : Less than 2 seconds t10-90 response
    NH3 : Less than 5 seconds t10-90 response

*1 For details of verification condition, refer to the specification table.

  • Development of new NOx after-treatment systems, such as urea-SCR, CRTs and LNTs
  • As an R&D tool for new regulations - Certification or reporting of GHG*2 emissions (EPA)
  • Direct measurement of N2O from Heavy-duty and non-road engines - R&D related to Euro VI
  • Direct measurement of NO2・NH3 from Heavy-duty engines

*2: GHG = Greenhouse Gas

  1. Mid-IR laser with long optical path provides ultra high sensitivity
  2. Dual path in a single cell gives wide dynamic measurement range
  3. Minimum interference from co-existing components : High resolution spectrum (up to 0.001cm-1)
  4. Ease of use : No liquid N2 required for detector

  • Sample Line Temperature: 113 ± 6℃
  • Response Time( t10-90):
    • NO・NO2・N2O : 2 seconds or less
    • NH3 : 5 seconds or less*
  • Dimensions / Mass
    • Main unit: W440×D660×H877 (mm)
    • Approx. 120 kg (excluding protruding objects)

* Verification condition: Flow NH3 gas (50 ppm) from sample gas inlet at flow rate 8 L/min;

Using a sample probe of 0.3 m, a heated filter and a heated line of 6 m.
