Walk-through Portal for Explosives
and Narcotics Detection
GE Security can deliver a key component of the total
checkpoint security solution with an EntryScan. A high-
throughput, non-intrusive walk-through portal that
enables rapid detection of both explosives and narcotics.
Microscopic traces of explosives can easily be detected
In addition, narcotics can also be identified in a
nonintrusive manner. EntryScan’s patented detection
technology allows for the efficient and accurate
detection of the most challenging substances.
• Airports and seaports
• Customs/border interdiction
• Military facilities
• Government buildings
• Nuclear plants
• Petrochemical facilities
• Public utilities
• High-security events
GE Security’s walk-through portal
can enable the detection of a broad
spectrum of concealed explosives
and narcotics in seconds.
Patented ITMS Technology Advantage
GE Security’s patented Ion Trap Mobility Spectrometer (ITMS®) technology can
detect a wide range of substances with accuracy and speed. ITMS detectors
can increase ionization efficiency, the main factor for determining detection
sensitivity. Due to the trap and membrane design, ITMS technology operates
well in dusty and humid high traffic areas, maintaining its precision
performance even in harsh “real world” environments.
Leading Sample Collection Technology
GE’s patented Ion Trap sample collection system takes advantage of a
natural airflow phenomenon called the “human convection plume.” This
eliminates the need for forced air from a fan, which would stir up contaminants,
dirt and dust, and enables the EntryScan to acquire cleaner samples for
higher detection sensitivity. This design requires fewer moving parts resulting
in quieter operation, reduced weight and improved long-term reliability.
Easy Operation and High Throughput
The EntryScan automatically controls traffic with a clear visual prompt,
signaling individuals to enter the portal. If traces of
