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
