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: 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: 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: 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: 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.
