A gas-analysis sample injection system and method for transfer of sample gas from a gas-sample cylinder to an analyzer such as a gas chromatograph, providing a cabinet with a door and a cabinet vent, vent manifold, and vent exhaust, a carrier gas supply, a sample cylinder support bracket, a sample filter housing, and a sample injector valve with an injector-valve actuator. Controlled by a valve controller over valve-control lines, a carrier gas regulating valve and sample-cylinder inflow valve allow carrier gas at regulated pressure into the mounted gas-sample cylinder, and a sample-cylinder outflow valve and sample transfer valve allow flow of sample gas into the sample injector valve. A filter vent valve and injector-valve vent valve operate in coordination with the other valves to provide venting and purging of extraneous gasses.

Disclosed herein are methods and systems for capture and measurement of a target component. A fluid sampling tool for sampling fluid from a subterranean formation may include a sample chamber having a fluid inlet, wherein the sample chamber is lined with a coating of a material that can reversibly hold a target component.

A gas sample introduction device includes a sample container connection flow path, a sample loop and a first flow path switching valve, having a first state in which the pressurizing gas is supplied to the sample container connection flow path via the sample loop and a second state in which the pressurizing gas is supplied to the sample container connection flow path without via the sample loop. A leak check method includes a first determination step of determining whether or not there is a gas leak by setting the first flow path switching valve to a first state and a second determination step of identifying a location of a gas leak by performing a second determination of whether or not there is a gas leak by setting the first flow path switching valve to a second state, when there is a gas leak in the first determination step.

A system for collecting a biological sample from a passenger cabin includes a collector for collecting particulate samples positioned within at least one of an outlet flow path or a recirculation flow path. The system includes at least one of an outflow valve positioned in the outlet flow path downstream from the collector or a HEPA (high efficiency particulate air) filter positioned in the recirculation flow path downstream from the collector. A method for collecting particulates from cabin air includes capturing particulates in at least one of an outlet flow path or a recirculation flow path with a collector for a period of time, removing the collector from at least one of the outlet flow path or the recirculation flow path for testing, and inserting a clean collector into at least one of the outlet flow path or the recirculation flow path for use during another period of time.

A gas sample introduction device includes a sample container connection flow path, a sample loop and a first flow path switching valve, having a first state in which the pressurizing gas is supplied to the sample container connection flow path via the sample loop and a second state in which the pressurizing gas is supplied to the sample container connection flow path without via the sample loop. A leak check method includes a first determination step of determining whether or not there is a gas leak by setting the first flow path switching valve to a first state and a second determination step of identifying a location of a gas leak by performing a second determination of whether or not there is a gas leak by setting the first flow path switching valve to a second state, when there is a gas leak in the first determination step.

An air sampling device and method of sampling air. The device has a housing body and a retaining assembly for a sampling device. A plenum has a top end coupled to the housing body about an opening such that the plenum is in flow communication with the opening and receives air flow generally from the top end to the bottom end generally along the longitudinal length thereof. A flow connection is coupled to the bottom end of the plenum. A mass flow meter has an input coupled to the flow connection and is in flow communication with the plenum via the flow connection. A blower is configured to draw air past the sampling device, through the opening, and through the plenum, such that a measuring portion of the air flows through the flow connection and through the mass flow meter, which measured the flow rate of the measuring portion.

A system for determining the gender and/or fertility status of avian eggs including a sampling apparatus and an electromagnetic radiation transmitter and detector. In certain embodiments, the transmitter operates in the terahertz range. The sampling apparatus can be coupled to an avian egg. The sampling apparatus includes a vacuum source, a gas collection device, and a membrane that can be positioned in the passageway coupling the vacuum source to the gas collection device. The membrane is capable of capturing volatile organic compounds. The sampling apparatus applies a vacuum from the vacuum source to the gas proximate to the avian egg and directs the gas captured from the vicinity of the egg toward the membrane. Subsequently, the membrane is positioned within the electromagnetic radiation emitted by the transmitter, generating a spectrum which can be analyzed to determine whether the egg is fertile or infertile, and if fertile, whether the egg is male or female. In an embodiment, the captured volatile organic compounds are transferred to a sample chamber where the captured gas is analyzed.

A device determines an oxygen content of a headspace gas in a liquid-filled container. The device contains a piercer, a sampling tube, a piercing head on which the piercer and the sampling tube are disposed, a pump, a ring line, and a sensor unit disposed within the ring line and used to determine the oxygen content and/or an oxygen partial pressure of the headspace gas of the liquid-filled container. The ring line is configured such that the headspace gas of the liquid-filled container can be sampled via the piercer or the piercing head by use of the pump and can be returned into the headspace of the liquid-filled container via the sampling tube.

A regenerator vessel for adsorbing halogen-containing material from a regenerator vent gas stream has a plurality of catalyst nozzles disposed at a top portion of the regenerator vessel. A first gas outlet is associated with a chlorination zone, and a second gas outlet associated with a combustion zone.
