Urgency of liquid control
Use of dangerous liquids: petrol, acetone, nitromethane, etc. - allows to cause no less harm than use of arms or solid explosives.
2006: Attempt of terrorist act with use of liquid explosives, interdiction of LAGs carried onboard the aircraft. Threat of liquid explosives use in air and land transport was formulated.
![Page 3: Effective technology for mass screening of liquids AVK Lab LLC., Moscow, Russia](https://reader036.vdocuments.mx/reader036/viewer/2022062800/56649de35503460f94ada1a5/html5/thumbnails/3.jpg)
Measures assumed:
2006: no technical solution for fast & reliable detection of dangerous liquids,
International Civil Aviation Organization (ICAO) recommendation to interdict LAGs in hand luggage
Others followed
Urgency of liquid control

![Page 5: Effective technology for mass screening of liquids AVK Lab LLC., Moscow, Russia](https://reader036.vdocuments.mx/reader036/viewer/2022062800/56649de35503460f94ada1a5/html5/thumbnails/5.jpg)
Based on identification of: molecular compositions (gas analysis), density (X-Ray), optical properties (Laser optical spectroscopy), Microwave properties (microwave frequency systems)
Proved to be ineffective: Poor detecting capability (X-ray), Not applicable to hermetically sealed containers (gas analysis) Applicable to limited number of types of containers (Laser optical
spectroscopy and microwave frequency systems)
Poor performance of inspecting devices High rate of false alarms. Inspect limited type of containers Long detection time
Requires special training of staff

![Page 6: Effective technology for mass screening of liquids AVK Lab LLC., Moscow, Russia](https://reader036.vdocuments.mx/reader036/viewer/2022062800/56649de35503460f94ada1a5/html5/thumbnails/6.jpg)
Based on the fact that Flammable and explosive liquids has lower electrical conductivity and dialectical permeability compared to safe liquids
Uses method of Quasistatic electrical tomography for measurement of electrical and dialectical properties of liquids.
Designed in hand held and user friendly device
Novel approach

1. Alternating voltage is on active electrode.
2. Obtained signals are measured on receiver electrodes.
3. Permittivity and conductivity are calculated based on results independently on wall thickness.
4. The results are compared with a database of dangerous liquids.
5. Light and sound signals are obtained.
Operation principle
AVK Lab has developed break-through liquid screening technology based on quasistatic electrical tomography method
