    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: 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.
