摘要

Process for the peak integration for NDIR-detected gas analysis comprises producing one or more gases that absorb radiation in the infrared region of the electromagnetic spectrum, introducing the gases produced by means of a carrier gas to a non-dispersive IR spectrometer which detects and NDIR signal from the IR-absorbing gases, and forming a flat integral from the signal course. The gas flow flowing through the spectrometer is measured in the phase during the peak determination isochronous to each NDIR signal, the signal is multiplied with the gas flow added and the resulting mathematical products from the NDIR signal and the gas flow are integrated over the time period.
