HORIBA - Model MEXA-ONE-QL-NX - Laser Spectroscopic Motor Exhaust Gas Analyzer
From Automotive Emissions Measurement Systems
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.
For R&D of Advanced NOx After-Treatment Systems
- 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.
Applications
- 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
Key Features of QCL-IR Spectroscopy
- Mid-IR laser with long optical path provides ultra high sensitivity
- Dual path in a single cell gives wide dynamic measurement range
- Minimum interference from co-existing components : High resolution spectrum (up to 0.001cm-1)
- Ease of use : No liquid N2 required for detector
Sample Line Temperature: 113 ± 6℃
- Sample Line Temperature: 113 ± 6℃
- Response Time( t10-90):
- NO・NO2・N2O : 2 seconds or less
- NH3 : 5 seconds or less*
