Proces FTIR analyzers

Fourier Transform Infrared Spectroscopy (FTIR) is an alternative way to incorporate infra-red spectra. The infrared light is passed through an interferometer. The signal is directly measured and showed by a computer.

Because an interferometer is cheaper than a monochromator, is a FTIR instrument not only faster but also cheaper than a traditional device. For these reasons almost all modern infrared spectrometers are of the FTIR type.

Simultaneous, real-time measurement of multiple components, wherein no condensation occurs. The measurements happen quickly and accurately.
For calibration, there is no span gas required, only a zero-point calibration is sufficient. The calibration is done on the basis of physical constant (absorption of the gas molecule)
The concentration of water is measured simultaneously·
Results can be displayed both on dry and on wet basis
All information is stored as a whole spectrum.

Component	Min Range	Typical	ppm->mg/Nm3
H20	0-5 Vol-%	0-25 Vol-%
CO2	0-10 Vol-%	0-20 Vol-%
CO	0-60 ppm	0-500 ppm	1 ppm = 1,25 mg
N2O	0-50 ppm	0-100 ppm	1 ppm = 1,96 mg
NO	0-150 ppm	0-300 ppm	1 ppm = 1,34 mg
NO2	0-100 ppm	0-300 ppm	1 ppm = 2,05 mg
SO2	0-25 ppm	0-100 ppm	1 ppm = 2,86 mg
NH3	0-20 ppm	0-100 ppm	1 ppm = 0,76 mg
