    • Sampling devices are used to obtain samples of fluids to be analyzed and to determine the composition of the fluid in the sampled environment. A sampling apparatus with an inflatable sample bag used to collect and store liquid, air, vapor, and or gas samples by drawing the sample into the bag through an inlet, a sorbent tube, cassette, and/or other collection media is described. The means for extracting the sample and moving it into the sample bag comprises means for expanding the volume of a sample bag and creating a vacuum or reduced pressure within the sample bag. The means for expanding the include separating walls of a sample bag by use of gravity, pneumatic pressure, a biasing force, hydraulic force, for example or increasing the volume of a sample bag retaining container by such forces. Such sampling apparatuses do not require use of a sampling pump.
    • 采样装置用于获得要分析的流体样品,并确定采样环境中流体的组成。 描述了一种具有可膨胀样品袋的采样设备,其用于通过将入口,吸附剂管,盒和/或其它收集介质将样品拉入袋中来收集和储存液体,空气,蒸汽和/或气体样品。 用于提取样品并将其移动到样品袋中的装置包括用于扩大样品袋的体积并在样品袋内产生真空或减压的装置。 用于通过重力,气压,偏压力,液压力来扩大样品袋的分离壁的装置,例如通过这些力增加样品袋保持容器的体积。 这种取样装置不需要使用取样泵。

    • Sample bags having at least one multilayer wall are described. The multilayer wall may include an inner layer and a sealing layer. The sealing layer is outside of the inner layer and forms a seam around at least a portion of the sample bag. In certain embodiments, the inner layer comprises a patterned periphery. The patterned periphery extends into the seam to provide the inner layer with a mechanical stability. The inner layer may be a thin metal foil or a plastic film and the sealing layer may include a sealing surface of a thermoplastic, wherein the thermoplastic of each sealing layer may be fused to form a seal around the periphery of the sampling bag. The sample bag thereby an inner layer with a low permeable, low adsorption layer coupled with a second layer providing an effective seal results in a sample bag with improved sample gas stability.
    • 描述具有至少一个多层壁的样品袋。 多层壁可以包括内层和密封层。 密封层位于内层的外侧,并在样品袋的至少一部分周围形成接缝。 在某些实施例中,内层包括图案化外围。 图案化的外围部分延伸到接缝中,为内层提供机械稳定性。 内层可以是薄金属箔或塑料膜,并且密封层可以包括热塑性塑料的密封表面,其中每个密封层的热塑性材料可以被熔合以形成围绕取样袋周边的密封。 因此,样品袋具有低渗透性低吸附层的内层,其与提供有效密封的第二层结合,导致具有改进的样品气体稳定性的样品袋。
