摘要: A method for introducing standard gas into a sample vessel is generally disclosed comprising providing a vessel containing a sample gas and a receptacle with a vessel port, such as sampling needle, pressurizing the vessel with a carrier gas, and introducing a volume of standard gas into the flow path of the carrier gas being used to pressurize the vessel when the vessel port of the receptacle is located within the vessel. In some embodiments, a rotary valve is loaded with the standard gas, and the valve is brought into fluid communication with the flow path of the carrier gas when the vessel port is within the vessel.

摘要: A system and method for extracting headspace vapor is generally disclosed comprising pressurizing a vessel containing headspace vapor with a carrier gas and subsequently venting the sample mixture through an adsorbent trap and out a vent. A flow controller is employed to gradually increase the flow therethrough as the pressure drops as a result of the gradual depletion of headspace vapor in the vessel and, in certain embodiments, the flow controller maintains a constant flow rate. Due to the time saved, in some embodiments, multiple pressurization-venting cycles are implemented to maximize the amount of vapor extracted from the vial. Due to the constant flow rate, in certain embodiments, the pressure decay is monitored and compared to reference values in order to determine whether the sample vessel has a leak or other defect.

摘要: A flow control system, method and device for performing thermal desorption is provided. In one embodiment, the system includes a first flow path in which gas flows from a first carrier gas inlet, through a first vessel in a first direction at a first flow rate to adsorb analytes on an adsorbent of said first vessel; a second flow path in which gas flows from a second carrier gas inlet, through said first vessel in the first direction at a second flow rate to further adsorb the analytes on the adsorbent of said first vessel; a third flow path in which a carrier gas flows through said first vessel in a second direction to carry desorbed analytes out of said first vessel; and wherein the second flow rate of carrier gas through said first vessel is greater than the first flow rate of carrier gas through said first vessel.

摘要: Certain configurations of a gas chromatography system comprising an internal gas generator are described. In some instances, the gas chromatography system may comprise an internal hydrogen generator to provide hydrogen gas to a chromatography column for separation of analyte species. In certain examples, the gas chromatography system can be operated without any external gas inputs.
