The invention relates to an apparatus and method for measuring isotopic ratios in gaseous samples by NDIR spectroscopy. The apparatus and method provide four separate optical paths for separate measurement of each of two isotopes relative to a reference signal, using spectrally resolved infrared radiation. The design permits the measurements to be made accurately without significant time lags between measurements, and without interchanging of cells or filters.
L'invention se rapporte à un appareil et à un procédé de mesure de rapports isotopiques dans des échantillons gazeux par spectroscopie d'absorption non dispersive dans l'infrarouge (NDIR). Ledit appareil, ainsi que le procédé associé, utilise quatre chemins optiques distincts pour effectuer des mesures distinctes de chacun des deux isotopes par rapport à un signal de référence, au moyen d'un rayonnement infrarouge ayant subi une réduction de son domaine spectral. Cette conception permet d'effectuer des mesures de grande précision sans délai important entre les mesures, et sans échange de cellules ou de filtres.
