... and then full three-dimensional volumes can greatly improve the ability to determine explosive threats by identifying certain shapes or patterns, such as wires, batteries, or detonators, as well as measure the volume of the material in question. The additional geometrical information supplements the material x-ray attenuation information and results in a more specific discrimination of explosive materials.

... Sample analysis techniques employ a variety of chemical separation and detection methods including gas chromatography, chemical luminescence, and ion mobility spectrometry. These methods estimate the molecular weight, electron affinity, and various other chemical properties of the vapor or particulate matter collected (NRC, 1993, 1996~.
