Explosive Detection
However, explosive trace portals overlap
the capabilities of whole body imaging and
address many of the detection loopholes
present in whole body imaging. For
example, it is possible for terrorist teams to
subdivide bomb-making materials
amongst several people, so the quantities
are too small to be detected by imaging,
but ETPs would detect traces from these
small explosive quantities used in a team
terrorist effort.
According to Syagen, its Guardian

explosives trace detection portal uses
mass spectrometry to detect traces of Syagen’s Guardian

second blast of air from up to 20 jets
blow onto the person. There is then an
intake at the bottom of the portal which
sucks in air and concentrates particles
and vapour. This concentrator has a
heating source which subsequently
vapourises the sample. It is then drawn
into the MS analyser. The entire process
from passenger entry to analysis takes
around 16 seconds in total.
On the other hand, explosive detection
