MEXA-1400QL-NX

Simultaneous Measurement of
Four Nitrogen Compounds with High Accuracy
 - For Certification and R&D of advanced NOx after-treatment systems

The MEXA-1400QL-NX is an exhaust gas analyzer for four nitrogen
compounds simultaneously,i.e. NO, NO₂, N₂O and NH₃,
utilizing mid-infrared Quantum Cascade Laser technology.
By using the high power, high resolution lasers, the analyzer can measure
each component accurately,even in low concentrations,
with minimum interference from other components in engine exhaust gas.
It is suitable for the R&D measurements related to the latest legislative
concerns (NO₂, N₂O and NH₃) as well as the development of
exhaust after-treatment devices.

Applications

• For developing new NOx after-treatment systems such as urea-SCR,
  CRTs and Lean NOx Traps (LNTs)
• As an R&D tool for new regulations
  - For EPA GHG: highly accurate, measurement of N₂O
  - For Euro VI HDD: NH₃ measurement for active NOx removal devices 

Advantages

• Simultaneous real-time measurement of four nitrogen compounds
  (NO, NO₂, N₂O and NH₃)
• Potential to be integrated in the HORIBA MEXA-7000 system^※
• Wide dynamic range:
  e.g. NO can be measured at the range of 0-10 ppm to 0-5000 ppm
• Fast response measurement with the analyzer installed near the engine
  NO/NO₂/N₂O: less than 2 seconds as T₁₀-T₉₀ response
  (at the flow of 8 L/min)
