    Abstract: A vacuum jacketed gas line adaptor with a flange cover for an existing pipeline sample take-off probe encasing a sample line and hermetically sealed to a vacuum valve housing having an sealable access port and containing a vented bleed valve and a block valve, fluidly connected to the sample line and a length of vacuum jacketed tubing sealing connected to the valve housing and in vacuum communication therewith, where the vacuum jacketed tubing surrounds the sample line to provide thermal isolation from the ambient for the sample line to a sample vaporizer.

    Abstract: A multi-stage pressure regulation system, device with enhanced thermal distribution for reducing the pressure of gas passing through a gas sample conditioning system. The device and method allow for automatic and/or manual configuration settings for regulating different types of gas having different profiles while still avoiding dew point dropout thereby ensuring accurate sample analysis at a downstream analyzer. The pressure regulating device includes a housing having a core, a vapor sample input port, a plurality of openings on an upper surface, a plurality of pressure regulating valves configured to reduce the pressure of a vapor sample, an assembly having a base and substantially central stem orthogonal to the base and extending axially therefrom, the stem being disposed within the core, and an adjunct for enhanced distribution of thermal energy from the heating device to the plurality of pressure regulating valves.

    Abstract: A vaporizer device and associated methodology for providing accurate sampling through substantially efficient, complete and uniform single pass vaporization of a liquid sample by avoiding liquid pre-vaporization and downtime attributable to system damage from incomplete vaporization, particularly in the distribution, transportation, and custody transfer of natural gas. The vaporizer device includes at least one input port for receiving a liquid sample, a channel for directing the liquid to a vaporizer core and a heating assembly within the vaporizer core configured to flash vaporize the liquid sample. The vaporized sample can then be passed to an outlet for sample analysis.

    Abstract: A cryogenic liquid sampling system including a chamber having affixed therein a sample pump to pull a cryogenic liquid sample from an external source and an enclosure. The enclosure includes a supply port to receive an input stream of a gas, an input port connected to the chamber via a vacuum line, a sample pump port connected to the chamber via a pump line and configured to feed therethrough gas received at the supply port to the sample pump, a vacuum device connected to the input port and configured to generate a vacuum within the chamber by pulling air from the vacuum line, and processing circuitry to control the vacuum device and the sample pump to perform transfer of a cryogenic liquid sample from the external source to an external device.
