Paper Abstract

The performance of a multi-component IR-spectrometer (Perkin-Elmer, mode. MCS 100) has been evaluated with regard to the influence of possible interferences from the gaseous compounds present in a flue gas. The spectrometer is configurated for measurement of NO, NO2, CO, CO2, N2O, NH3 and H2O. A theoretical examination of the absorption spectra of possible interfering hydrocarbons has been carried out together with a theoretical estimation of the errors introduced during the compensation for interferences due to incorrectly measured absorbances. The accuracy of the automatic compensation routines for interferences used by the spectrometer has been investigated by laboratory test runs including potential interferences from components not measured by the analyzer. The response time of ammonia has been studied in the laboratory and during field measurements.
