FTIR Motor Exhaust Gas Analyzer

MEXA-ONE-FT - HORIBA, Ltd.

The MEXA-ONE-FT Series simultaneously measures concentrations of multiple components, including NH3, N2O, CH4, CO and CO2, in undiluted exhaust gas using the Fourier transform infrared (FTIR) method in combination with a multivariate analysis algorithm. It incorporates HORIBA's proprietary compact interferometer which yields superior performance and high accuracy.The system complies with NH3 testing requirements of Euro VI, the EU regulation for heavy duty emissions testing.The MEXA-ONE-FT can be calibrated according to customer requirements with up to 6 component sets to cover a wide range of applications.FTIR spectroscopy allows the direct measurement of NO2 emissions and the independent quantification of individual hydrocarbon species. This makes the MEXA-ONE-FT system an ideal solution for detailed research and development tasks.Due to the measurement principle, the time-consuming daily span gas calibration is omitted.In addition, usability and flexibility are realized by “HORIBA ONE PLATFORM” which enables to extend the system with other ONE analyzers to a complete solution suitable for both certification and R&D purposes.

Laser Spectroscopic Motor Exhaust Gas Analyzer

MEXA-ONE-QL-NX - HORIBA, Ltd.

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.

Motor Exhaust Gas Sulfur Analyzer

MEXA-1170SX - HORIBA, Ltd.

The MEXA 1170 SX is a new instrument used to measure sulfur for after treatment and transient lubricant oil consumption. The analyzer uses ultraviolet fluorescence (UVF) for detection and it can be operated in a total sulfur mode, analyzing sulfur oxides, hydrogen sulfide and all organic sulfur compounds. An inorganic sulfur mode will analyze hydrogen sulfide and the sulfur oxides. The final operational mode will analyze just the sulfur oxides. Any one of these modes can be selected by the user from a front panel interface.
