FTIR Exhaust Gas Analyzer
FTX-ONE is a fast response and compact size FTIR analyzer for the simultaneous measurement of multiple components of engine exhaust gases.
The FTX-ONE offers a 5Hz sampling rate and simultaneously measure the concentrations of multiple components including NH3, CH4, and CO2, from un-diluted exhaust gas using the Fourier Transform Infrared (FTIR) method in combination with multivariate analysis algorithm.
