    摘要: A fluid sampling device is provided comprising an elongated housing having a longitudinal axis, a plurality of alternating sorbent units and spacer units disposed longitudinally through the housing and slidably movable therethrough along the longitudinal direction, and means for individually and sequentially exposing the sorbent units to a fluid. The adsorbed components can then be desorbed and analyzed to provide composition data of target compounds in a fluid, e.g., a gas, over a period of time.

    摘要: A sampling device is disclosed. The sampling device is portable and capable of taking two samples in parallel. The sampling device can include two filter locations that are subjected to similar environmental conditions. The sampling device design facilitates easy assembly and disassembly, and can be designed so that a single filter holder design can be used in both filter locations.

    摘要: A system (100) and method for detecting contaminants in parcels or other mailings (110). The contaminants, either genuine or hoax, are detected using the system (100) that includes a jogger (140) that shakes the parcels or other mailings (110). The system (100) further comprises a particle sampler (170) that analyzes the air flow created over the parcels (110) while the parcels are shaken. The system (100) and method preferable includes a parcel opening cutter (120) and a ram (148) for compressing during the shaking of the parcels. The air flow is sampled in order to detect whether or not a plurality of opened parcels is suspected of including contaminants such as biological threat material.
