    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: Disclosed are systems and methods that include providing a vessel having an inlet and an outlet for communicating a carrier gas through the vessel; determining a differential pressure between the inlet and the outlet for a known flow rate at the outlet; and, determining a unit flow per unit pressure based on a ratio of the flow rate and the differential pressure. In certain embodiments, the flow rate at the outlet is established by controlling the flow rate of the gas. In some embodiments, the methods and systems can include a viscosity in the ratio, determining a flow rate at ambient pressure using a factor based on a ratio of a gas pressure at the output and ambient pressure, and/or, determining a flow rate at ambient temperature using a factor based on a ratio of a temperature at the output and ambient temperature.

    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.
