At the opposite of the FTIR approach where the Fourier transform needs moving optical components, the Fourier transform in the UV range is done by solid state optics and electronic circuits, which constitutes a more reliable solution for a lower cost. The selectivity of the analyser is guaranteed by the typical UV spectrum of each gas.

Based on UV Fourier Transform for high selectivity and stability and other algorhythms
Ultra-fast response time (< 1 sec)
High speed DSP for signal extraction
No risk of interferences or quenching effects with CO, CO2, H2O
No converter, no maintenance
10-years lamp lifetime
