    摘要: 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.

    摘要: 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). The security inspection apparatus of the present invention can perform the sampling easy, rapidly and effectively and perform the inspection accurately and rapidly without destroying and unpacking an object to be inspected, and thus is suitable for requirements of on-site rapid inspection of forbidden items in the airport, customs and the likes.
