SEADM’s systems deliver unique advantages for the detection and analysis of trace and ultra-trace vapors for security applications:
- Lowest limits of detection currently available: 0.01 ppq (parts per quadrillion), for RDX explosive.
- Unless other ion mobility devices, SEADM’s equipment operates in the space (not in the time) domain, enabling transmission efficiencies of about 50% vs. typically 0.1% of common drift tube techniques.
- Full automated analysis delivering measurements in short time intervals (5 seconds under development).
- Unbeatable probability of detection and false alarm rate in the detection of concealed explosives.
Based upon these unique performance advantages, SEADM’s equipment allows the protection of critical infrastructures such as airports and energy facilities from terrorist attacks (including suicide bombers), in those applications where other technologies simply do not work.
Our integrated D-LFSESI/DMA/MS Vapor Analysis System can be used in two modes: off-line (sample taken away from the analyzer) or on-line (sample taken from the laboratory). Likewise, if you have a mass spectrometer we can build a complete system for you linking it with our Vapor Analyzer Front End.
For the off-line operation, the High Volume Sampler (HVS) allows vapor collection separation from analysis. It delivers an initial filtration stage through filter coating selection, along with concentration. The filter is taken to the laboratory and inserted in the Analyzer, where the vapors are desorbed, ionized separated by mobility and finally analyzed in mass and mass fragment. For special applications requiring fast measurement the process of filter manipulation can be seemingly robotized.
SEADM’s equipment has been thoroughly applied, in collaboration with its affiliated company SEDET as well as reference stakeholders, for the detection of concealed explosives through the detection of their emanated vapors at ultra-trace levels:
Detection of explosives in cargo
For this application, the equipment is currently undergoing certification within the H2020-SME project ACES, in cooperation with relevant stakeholders in the field
Delivering maximum performance in the vapor detection of threats (highest probability of detection and lowest false alarm rate) without slowing passenger flow down (the results, for the moment need to remain confidential).
Screening of cars with internal sampling
Example of application: EFFISEC project (information of the system goes from 4:03 to 4:50)
