    Abstract: The invention provides a method and apparatus for detecting minority gaseous species in a mixture by light-emission spectroscopy by means of an optical spectrometer (8), in which the radiation emitted by a plasma (4) present in the gas mixture for analysis is used and, in the spectrum of said radiation, lines are identified of a majority gaseous species that present amplitudes that are sensitive to the presence of a minority species, and information about the concentration of a minority gaseous species is deduced from the amplitude(s) of said sensitive line(s). This makes it possible to monitor minority gaseous species in real time.

    Abstract: Validation verification data quantifying an intensity of light reaching a detector of a spectrometer from a light source of the spectrometer after the light passes through a validation gas across a known path length can be collected or received. The validation gas can include an amount of an analyte compound and an undisturbed background composition that is representative of a sample gas background composition of a sample gas to be analyzed using a spectrometer. The sample gas background composition can include one or more background components. The validation verification data can be compared with stored calibration data for the spectrometer to calculate a concentration adjustment factor, and sample measurement data collected with the spectrometer can be modified using this adjustment factor to compensate for collisional broadening of a spectral peak of the analyte compound by the background components. Related methods, articles of manufacture, systems, and the like are described.

    Abstract: Non-dispersive infrared (NDIR) sensing systems employ a NDIR sensor coupled to a microprocessor to determine gas concentrations by employing slope-based methodologies that compensate for pressure variations, temperature variations, or both, which may compare NDIR signals with calibrated data. NDIR sensor systems may employ means for limiting the system peak current demand providing for the portability and scalability of the system. In NDIR sensor systems calculating gas concentrations using calibration data, the phase of the change in the NDIR output signal in response to a change in the infrared source emitter level may be measured as part of the calibration process.
