    摘要: The invention discloses a safety inspection detector and a goods safety inspection system. The safety inspection detector at least comprises a circuit board, a first housing, a second housing, a detection module and a connecting interface. The detection module and the connecting interface are mounted on the circuit board. The first housing is pressed and connected to a first surface of the circuit board, and the second housing is pressed and connected to a second surface of the circuit board. The first housing and the second housing can hermetically wrap the detection module and electronic devices on the circuit board, but bypass the connecting interface to realize leading-out and connection with related interconnected cables by utilizing the connecting interface. The housings can be used for sealing and protecting sensitive electronic devices in the detector, thus being moisture proof and preventing interference.

    摘要: A GC-IMS system is disclosed in embodiments of the present invention. The system comprises a sample transfer device. The sample transfer device connects the gas chromatograph to the reaction region and, the sample from the gas chromatograph is transferred to the reaction region by the sample transfer device directly, instead of not through the ionization region. With the GC-IMS system, generation of sample molecular ion fragments can be avoided so that the spectrum is brevity and is easily identified; moreover, the application field of the GC-IMS system is extended to a range of analysis of organic macromolecule samples which have a high polarity, are difficult to volatilize, and are thermally instable. On the other hand, the GC-IMS system overcomes the defect of ion destruction due to neutralization reaction among positive and negative ions so as to evade the detection.
