    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 limited access space inspection system comprising: a sensing device for carrying out sensing over a region in the limited access space, a mounting for mounting the sensing device to scan about the limited access space and a scanning control unit, associated with the sensing device, for controlling the sensing device to scan about the limited access space. The device is particularly useful for improving by automation, security checks, customs checks and safety checks involving such awkward to access spaces. The sensing device may be an imaging device, or a sensor for detecting traces of chemical substances.

    摘要: A method and apparatus for detecting trace amounts of a target substance carried by the object, by: applying to the object a flow of air which has been pre-heated, to dislodge substances carried by the object; collecting the heated air after applied to the object; and analyzing the collected heated air for the presence of the target substance. Preferably, a marker substance is introduced into the air before applied to the objects, and the collected heated air is analyzed also for the presence of the marker substance.
