GE Security says it Itemiser DX desktop explosives trace detection equipment has successfully completed rigorous TSA certification testing in the DHS Transportation Security Laboratory and in a live airport environment. As the latest GE trace detector to receive TSA certification, the Itemiser DX provides threat substance identification, including even the most complex explosive substances from a single sample. The lightweight detector simultaneously analyzes both positive and negative ions, allowing for explosive contraband detection. Similar in appearance to the GE Itemiser3, this trace detector was designed to be more sensitive and can identify a larger number of threat substances. The Itemiser DX uses advanced trace technology and provides results in seconds. The Itemiser products incorporate Ion Trap Mobility Spectrometer (ITMS) technology.
