    Abstract: A differential absorption spectrum for a reactive gas in a gas mixture can be generated for sample absorption data by subtracting background absorption data set from the sample absorption data. The background absorption data can be characteristic of absorption characteristics of the background composition in a laser light scan range that includes a target wavelength. The differential absorption spectrum can be converted to a measured concentration of the reactive gas using calibration data. A determination can be made whether the background composition has substantially changed relative to the background absorption data, and new background absorption data can be used if the background composition has substantially changed. Related systems, apparatus, methods, and/or articles are also described..

    Abstract: A measuring device for determining the concentration of such gas components from a gas mixture, which includes collision dilation of the absorption lines constituting the absorption spectral bands for measuring objects. The device comprises a non-dispersive concentration measuring sensor (20), which includes: a measuring chamber (6) containing a gas mixture to be analyzed; a radiation source (17) for emitting over a wavelength range which includes an absorption spectral band used in concentration determination; a detector (18) receiving radiation that has passed through the measuring chamber and for producing a first signal (7) therefrom; as well as an optical bandpass filter (16) positioned between the detector and the radiation source. The measuring device further comprises a second measuring sensor (4) for identifying the viscosity or some other viscosity-related feature of a gas mixture to be analyzed and for producing a second signal (9). Both signals (7, 9) are delivered to a calculating unit (8), which uses at least a second signal for performing the corrections required for the first signal. In addition, the device is provided with a display means (10).

    Abstract: A method and apparatus for the determination of spectral samples is disclosed wherein spectral measurements are taken, normalization of the spectral measurements takes place, and a bilinear modeling is performed to extract spectral data. Once this data is derived, the interference quantitization levels are determined using multiple linear regression analysis, and are then removed from the sample readings in order to determine a more precise level of analyte spectra, such as analyte levels of glucose in serum or whole blood.

    Abstract: A particular area or areas are monitored for the presence of gaseous materials, particularly pollutants by analyzing background infrared radiation present in the selected area with a spectrometer and making the results of this analysis available in a form understandable to the person or device monitoring the area for the presence of specified gaseous materials. The results of the spectrometric analysis may, for example, be displayed on a video unit or they may be printed. Apparatus useful in the practice of this invention generally includes an interferometer of the Michaelson-Morely type having specific optical characteristics, a sensitive infrared detector, electronic data processor, and a device which records and/or displays the results of the determination(s).
    In a preferred embodiment, no radiation concentrating or focusing elements are used ahead of the beamsplitter of the Michelson-Morely interferometer, said interferometer having imaging optics which, combined with detector size, results in the optical field of view being essentially no larger than the area of the remote source employed.

    Abstract: A detector has a sensor responsive to a first wavelength, a sensor responsive to a second wavelength, and a sensor for collecting reference readings. A gas sample is analysed to obtain readings corresponding to the first wavelength, the second wavelength and a reference. A first absorption figure is calculated using the first reading and the reference reading, and a second absorption figure using the second reading and the reference reading. A lineariser function is applied to the first and second absorption figures to calculate first and second concentration figures. The sensor for each wavelength is calibrated for detecting the first gas such that the data collected at each wavelength gives the same reading when only the first gas is present. The ratio of the first concentration figure to the second concentration figure is used to identify whether only the first gas is present.
