摘要： A sample cell (100) can be designed to minimize excess gas volume. Described features can be advantageous in reducing an amount of gas required to flow through the sample cell during spectroscopic measurements, and in reducing a time (e.g. a total volume of gas) required to flush the cell (100) between sampling events. In some examples, contours of the inner surfaces (202) of the sample cell that contact the contained gas can be shaped, dimensioned, etc. such that a maximum clearance distance (120) is provided between the inner surfaces (202) at one or more locations. A device, method and an apparatus are described.

摘要： A valid state of an analytical system that includes a light source (102) and a detector (106) can be verified by determining that deviation of first light intensity data quantifying a first intensity of light received at the detector from the light source after the light has passed at least once through each of a reference gas in a validation cell (114) and a zero gas from a stored data set does not exceed a pre-defined threshold deviation. The stored data set can represent at least one previous measurement collected during a previous instrument validation process performed on the analytical system. The reference gas can include a known amount of an analyte. A concentration of the analyte in a sample gas in a measurement cell (112) can be determined by correcting second light intensity data quantifying a second intensity of the light received at the detector after the light passes at least once through each of the reference gas in the validation cell and a sample gas containing an unknown concentration of the analyte compound. Related systems, methods, and articles of manufacture are also described.

摘要： A spectrometer includes a light source that emits a beam into a sample volume comprising an absorbing medium. Thereafter, at least one detector detects at least a portion of the beam emitted by the light source. It is later determined, based on the detected at least a portion of the beam and by a controller, that a position and/or an angle of the beam should be changed. The beam emitted by the light source is then actively steered by an actuation element under control of the controller. In addition, a concentration of the absorbing media can be quantified or otherwise calculated (using the controller or optionally a different processor that can be local or remote). The actuation element(s) can be coupled to one or more of the light source, a detector or detectors, and a reflector or reflectors intermediate the light source and the detector(s).

摘要： Detector data representative of an intensity of light that impinges on a detector after being emitted from a light source and passing through a gas over a path length can be analyzed using a first analysis method to obtain a first calculation of an analyte concentration in the volume of gas and a second analysis method to obtain a second calculation of the analyte concentration. The second calculation can be promoted as the analyte concentration upon determining that the analyte concentration is out of a first target range for the first analysis method.

摘要： Scrubber media for reactive gases, that can include but are not necessarily limited to hydrogen chloride (HCl), hydrogen sulfide (H2S), hydrogen fluoride (HF), and ammonia (NH3), can include reactive particles, potentially as small as nano-scale, that can optionally be suspended on macro-scale carrier particles. Reactive gases can be converted to non-volatile compounds by being passed through a bed of such scrubber media. Such scrubber media can be used to remove reactive gases from gas mixtures. Potential applications include differential absorption spectroscopy, air pollutant emission controls, and the like. Methods of preparing scrubber media are also described.

摘要： 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..

摘要： Low concentrations of water vapor within a background of one or more hydrocarbon gases may be detected and quantified using a differential absorption spectrometer. A dehydrated sample of the gas is used as a background sample whose absorption spectrum allows elimination of absorption features not due to water vapor in the gas. Absorption spectra may recorded using tunable diode lasers as the light source, these lasers may have a wavelength bandwidth that is narrower than the water vapor absorption feature used for the differential absorption spectral analysis.
