摘要： A method of using a spectrometer to produce corrected diamond Attenuated Total Reflectance (ATR) spectral data includes acquiring, using the spectrometer, an initial set of ATR spectral data for a sample pressed into contact with a diamond ATR crystals; numerically matching, using the spectrometer, a pressure dependent diamond artifact reference spectrum to a corresponding pressure dependent diamond artifact in the initial set of ATR spectral data; and numerically subtracting out the numerically matched pressure dependent diamond artifact reference spectrum from the initial set of ATR spectral data to yield a corrected set of ATR spectral data for the sample for output by the spectrometer.

摘要： An oxygen sensing system including an oxygen sensor, a microprocessor and one or more additional sensors for sensing parameters associated with the environment or with the oxygen sensor, accounts for one or more sensed conditions when calculating oxygen levels. The one or more sensors may sense conditions associated with environmental effects or effects of use that may cause the oxygen sensor to degrade over usage or over time. A baseline amplification and measurement circuit coupled to the oxygen sensor may enable the sensor to operate less frequently or for shorter periods of time, thereby increasing the life span, calibration hold time of the sensor, and reducing power requirements.

摘要： 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.

摘要： A method of determining a concentration of a gas in a sample and/or of the composition of a gas by means of a spectrometer includes measuring an absorption signal of the gas as a function of the wavelength. The wavelength substantially continuously runs through a wavelength range and is superimposed by a harmonic wavelength modulation, wherein the influence of the wavelength modulation on the absorption signal via the light source modulation properties and the detection properties of the spectrometer is dependent on the device properties of the respective spectrometer. The method includes converting the absorption signal into at least one first derivative signal; deriving a gas concentration measurement parameter from the first derivative signal; determining the concentration and/or composition of the gas from at least the gas concentration measurement parameter and from a calibration function compensating for influences of state variables of the gas and of the spectrometer properties.
