| titleOfInvention | Ndir apparatus and method for measuring isotopic ratios in gaseous samples |
| abstract | 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. |
