    Abstract: Concentrations of a target analyte in a gas mixture containing one or more background analytes having potentially interfering spectral absorption features can be calculated by compensating for background analyte absorption at a target wavelength used to quantify the target analyte. Absorption can be measured at a reference wavelength chosen to quantify the concentration of the background analyte. Using a background gas adjustment factor or function, the absorption measured at the reference wavelength can be used to calculate absorption due to the background analyte at the target wavelength and thereby compensate for this background absorption to more accurately calculate the target analyte concentration in real or near real time. Additional background analytes can optionally be compensated for by using one or more additional reference wavelengths.

    Abstract: The invention provides a method for identifying the impacts of interfering effects on experimental data. In particular, a method is described for identifying the impacts of unwanted auto-fluorescence, fluorescence quenching, and deterioration of a fluorescent sample under study on the collected experimental data. The data are analyzed whether or not said data fulfill certain criteria with respect to a threshold which is indicative for said interfering effect.

    Abstract: A concentration of a detector gas in a measuring gas containing an interfering gas is measured. A zero gas that is free of the detector gas and/or a test gas having a known concentration of the detector gas are supplied to an analyzer such as a non-dispersive infrared (NDIR) gas analyzer. Interfering gas is added to the measuring gas, the zero gas, and in some instances, to the test gas to an extent which allows the interfering gas to have a same concentration in each case.

    Abstract: A dual path analyzer and a single path analyzer are disclosed, each for determining the concentration of one or more gaseous components in a mixture of gases. The preferred analyzer is a single path instrument which includes a source of infrared energy, a detector for the energy, a sample cell for the gas mixture positioned between the source and detector, and a filter wheel having a plurality of filters and a source blocking device positioned between the sample cell and detector for sequentially interposing the filters and the source blocking device between the source and the detector. Means are provided for amplifying the output signal of the detector and for processing the signal to provide a direct readout display which indicates the concentration of the gaseous components being analyzed. The processing electronics preferably include provision for calibrating the analyzer with clean ambient air, for compensating for background levels of radiation, and for correcting the displayed output signal for the effects of absorption band interferences between two or more gases in the gas mixture. The structure of the dual path analyzer includes a source of infrared energy, a detector for the energy, a sample cell for the gas mixture, a cell for a reference gas, and optical path means between the source and detector for sequentially directing the source energy through the sample cell, the reference cell, and through neither cell. Processing electronics similar to the single path instrument can be incorporated to compensate for background radiation and absorption band interferences.

    Abstract: In an improved non-dispersive infrared (NDIR) gas sensor for differentiating gases in a gas mixture, a radiation source, for example having two LEDs (1,2), emits radiation having first (3) and second (4) emitted bands overlapping in frequency. A modulator (5) is configured to modulate the emitted radiation so as to provide each of the first and second emitted bands with a discrete modulation signal. After the radiation passes through a gas sample chamber (6) , a radiation detector, for example a photodiode (7) , receives the radiation. Demodulated (8) detection signals for each of the first and second emitted bands are used to differentiate gases in the gas mixture, by subtraction. The emitted bands may have different power from different LED areas or duty cycles. Epitaxially grown or coated filters (10,11) on the LEDs trim the bandwidth of the emitted bands .
