Abstract: This disclosure provides an area array detector, a detection method, and a corresponding container/vehicle inspection system, and relates to the field of ray scanning. The area array detector for the container/vehicle inspection system includes sparsely arranged detector assemblies, and a first detector assembly is different from other second detector assemblies; and a backplane for carrying and mounting detector assemblies, and the area array detector supporting scanning modes is enabled.

Abstract: A sampling device and an inspection apparatus are disclosed. In one aspect, an example gathering and sampling device includes a cylindrical outer housing and an inner housing disposed within the cylindrical outer housing, a cyclone chamber is formed between the cylindrical outer housing and the inner housing to generate a cyclone by injecting a gas flow into the cyclone chamber. The gathering and sampling device further includes an outer chamber body, and a plurality of gas injection orifices formed in the first inner housing end opening of the inner housing and configured to inject a gas towards a substantial center of a circular region defined by an end face of the first outer housing end opening of the cylindrical outer housing.

Abstract: The present invention discloses darkroom type security inspection apparatus and method. An apparatus comprises a housing constituting a closed darkroom, and assemblies disposed inside the housing. The assemblies disposed inside the housing are communicated by fittings or connectors and comprises: a sampling assembly comprising a sample collecting unit and a conveyer unit configured to convey an object to be inspected into the sample collecting unit; a sample processing assembly configured to concentrate and analyze the sample; and, an inspecting assembly configured to inspect composition of the sample by means of a gas chromatographic-ion mobility spectrometer (GC-IMS) or a separated ion mobility spectrometer (IMS).

Abstract: The present invention discloses a general sample injector, comprising a sample injection port mechanism, a sample injector shell, a vaporizing chamber, a heater, a temperature control unit, a carrier gas channel, a septum purge channel, a flow splitting channel, a coolant channel, a multichannel flow control valve and a temperature control unit. The general sample injector, equivalent to a “programmed temperature vaporizer” injector combining splitting/no splitting with cold column head sample injection, gives full play to the advantages of various sample injection modes, overcomes a plurality of disadvantages, and has higher practicability and better flexibility.
