Optoelectronic CO Concentration Analyser – Wavelength Selection
Strong absorption lines within 4,3 –5,6 μm band would allow measurement of low concentration of carbon monoxide at relatively short optical path length. The best choice for CO concentration measurement seems to be 1,55 – 1,60 μm band because of availability, good operation parameters and low price of semiconductor sources and detectors as well of weak spectra overlapping of mixture components and relatively strong CO absorption lines.
