摘要： Delivery of a test specimen vapor--carrier gas mixture into a gas chromatograph is accomplished by means of an apparatus including a barrel to receive a probe which serves to maintain the test specimen in contact with carrier gas within the barrel, a heating coil disposed around portions of the barrel housing the sample, and a compression seal releasably bearing against a portion of the probe to prevent air flow into and gas flow from the open end of the barrel.

摘要： Herein is disclosed an inlet liner for use within an injection port of a capillary gas chromatograph. The inlet liner can include a first fused quartz tube and a second fused quartz tube aligned along a common longitudinal axis; the outside surface of the first fused quartz tube affixed to the inside surface of the second fused quartz tube. In certain instances, the tubers are affixed at two points along the longitudinal axis thereby defining a hermetically sealed volume between the outside surface of the first quartz tube and the inside surface of the second fused quartz tube, wherein the hermetically sealed volume entrains a reactive surface.

摘要： An apparatus for detecting a presence of at least one analyte in a gas sample. The apparatus comprises a pump for drawing a gas sample from an ambient air, a passage having first and second ends, a chamber connected to the first end and containing a concentrating element for collecting at least one analyte from the gas sample, a chromatographic separator connected to a second end of the passage, and a gas source for streaming a carrier gas via the chamber to transfer the at least one analyte toward at least one chemical detector, via the chromatographic separator, in a first direction. The pump draws the gas sample via the chamber in a second direction and the first and second directions are substantially opposing to one another.

摘要： A vial feed device is equipped with a feed arm, which is positioned between a vial tray and an oven and below either of them and having a feeding housing unit and a cooling housing unit, and a vial up-and-down moving mechanism for placing and removing vials in and from vial tray and oven. Feed arm is rotationally driven by a drive motor to move a feeding housing unit, a cooling housing unit and up-and-down moving mechanism toward vial tray or oven. High-temperature vials in oven are housed in cooling housing unit until cooling time T elapses. After cooling time T elapses, cooling housing unit is moved to a lower part of vial tray by feed arm, to be returned to vial tray by up-and-down moving mechanism.
