FTIR Motor Exhaust Gas Analyzer

The Model 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 Model 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 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 which enables to extend the system with other ONE analyzers to a complete solution suitable for both certification and R&D purposes.
