Abstract: A detection assembly for a non-dispersive infrared multi-gas analyzer, comprises a beam splitter for dividing an infrared (IR)-radiation beam into reflected beam portion(s) and transmitted beam portion(s), two detector units both with at least two separate detectors respectively, and optical filters in front of the detectors. The detector units are positioned to receive the reflected beam portion and the transmitted beam portion, respectively. A detection assembly for a non-dispersive infra-red multi-gas analyzer comprises a beam splitter (3) for dividing an IR-radiation beam (R) into at least one reflected beam portion and at least one transmitted beam portion (R-T), first and second detector units (21, 22) both with at least two separate detectors respectively, and optical filters in front of the detectors. The detector units are positioned to receive the reflected beam portion and the transmitted beam portion respectively. The first and second detector units have at least one first detector (1a, 1b), being measuring detectors each provided with an optical measurement filter (5a, 5b), which has a transmission wavelength band in the range of the absorption band of a gas component, to affect that portion of the IR-radiation ending into the first detector. The detector units both have at least one second detector (2a, 2b), being reference detectors each provided with an optical reference filter (6a, 6b), which has a transmission wavelength range, within which the gas component does not have absorption, so as to affect that portion of the IR-radiation ending into the second detector. The first detector in the first detector unit and the second detector in the second detector unit are positioned to constitute a first independent single path analyzer channel (11). The second detector in the first detector unit and the first detector in the second detector unit are positioned to constitute a second independent single path analyzer channel (12). An independent claim is also included for a non-dispersive infrared measuring arrangement in a multi-gas analyzer, comprising: (1) a radiation source providing an IR-radiation beam; (2) a measuring chamber for receiving a gas mixture to be analyzed, and adapted to transmission of the radiation beam; (3) a beam splitter dividing the beam into at least one reflected beam portion and at least one transmitted beam portion; (4) at least a first and a second detector unit both with at least two detectors; and (5) optical filters positioned in the beam or beam portions ending in the detectors, the detector units being directed to receive the at least one reflected beam portion and the at least one transmitted beam portion respectively.
