Abstract: Systems and methods for skewed basis set fitting may include obtaining measured absorption data indicative of an amount of absorption of light by a sample gas at each of multiple frequencies, determining an absorption dependent cavity time constant indicative of a skew to the measured absorption data caused by light reflections within a cavity in which the sample gas is contained, obtaining reference absorption data including basis sets indicative of reference amounts of light absorbed by each of multiple gases at each of the multiple frequencies, skewing the reference absorption data based on the absorption dependent cavity time constant to generate skewed reference absorption data, and fitting the measured absorption data to the skewed reference absorption data to identify an amount of at least one constituent gas within the sample gas.

Abstract: Systems and methods for measuring a value of constituents in a mixed constituent gas having at least one broad band absorber constituent therein and at least one lock constituent are provided. The system uses a combination of integrated cavity output spectroscopy and cavity ringdown spectroscopy to determine the measurement values of constituents in a cavity of a spectrometer. Cavity ringdown in the presence of the at least one broadband absorber constituent and a reference concentration value are used to determine the constituent measurement values when the spectral width of the laser tuning range is overlapped by the absorption band of the broad band absorber in the cavity.

Abstract: Devices, systems, and methods for sampling of gases to determine information regarding leaks are disclosed. Balanced sampling can be achieved by application of an inlet having a gas permeable membrane covering the opening. Extending the opening for a length can provide additional coverage for gas sampling. Connection of gas sampling instruments with analysis systems can determine leak information for use in remedying leaks, for example, from industrial equipment such as pipelines.

Abstract: A fugitive gas detection system includes an inertial measurement assembly that measures a change in position of the inlet of a gas analyzer and applies a time slip to concentration data detected by an analyzer to generate a time series of the concentration of the gas in three-dimensional space. Applying statistical methods, the relative location of the source of the fugitive gas can be established from the time series. Additionally, in some embodiments, the data may be interpolated to establish a map of a plume of the fugitive gas.

Abstract: Systems and methods for efficiently identifying gas leak locations may include traversing, by an investigator and within a search area in which a gas leak has been indicated, a route defined according to at least one of a surge-cast algorithm or a surge-spiral algorithm. The systems and methods may also include sampling, with a gas detection device carried by the investigator, an environment along the route to identify a location of the gas leak.

Abstract: Technologies for rapid equilibration for water isotope analysis are disclosed. In at least one illustrative embodiment, a vaporizer may include an injection block that defines a chamber and a septum positioned over an inlet of the chamber to seal the chamber. The chamber may be configured to be fluidly coupled to a pump to develop a vacuum within the chamber, and the septum may be configured to receive a needle that is inserted into the chamber. A thermally conductive wool may be positioned within the chamber and may be configured to receive a tip of the needle.

Abstract: A visualization system for visualizing gas leak detection data including a processor in communication with at least one memory device is provided herein. The processor is configured to receive, from one or more sensors, gas measurement data for a plurality of measurement locations within a survey area; receive, from the at least one memory device, a geographic representation of the survey area; determine, based upon the gas measurement data, estimated gas source locations of the plurality of measurement locations; and apply a smoothing algorithm to the estimated gas source locations to create a multi-dimensional density plot.
