LQtest Presentation ICAO 2009

AVK Lab LLC., Moscow, Russia
Effective technology formass screening of liquids
20th meeting of Aviation Security Panel
March 2009

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 transport was formulated.

Measures assumed:
2006: no technical solution for fast & reliable detection of dangerous liquids,
ICAO recommendation to interdict LAGs in hand luggage
Urgency of liquid control

What should the liquid screening technical solution be like:
The equipment for detection of dangerous liquids should be:
Easy-to-use
Suitable for mass screening
Fast and reliable at the analysis
The technology of liquid screening detection should provide:
Safety of flights
Comfort of passengers at checking

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
Liquid screening technologies existing today:

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

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

LQtest – robust and reliable liquid screening technical solution
High speed and accuracy of the analysis,
Detection of a vast list of liquids,
Possibility to provide mass screening of containers of various forms, colors and materials
LQtest device will prevent carrying dangerous liquids aboard the aircraft, provide safe, comfortable for passengers, reliable and fast mass screening of liquids
in any nonmetallic vessels,
at any environmental conditions,
at any level of transport congestion

Implication of LQtesttechnology
The technology is tested more than on 800 liquids, among them: - beverages; - foodstuff; - perfumery, cosmetics; - medical drugs; - household liquids: washing-up liquids, solvents; - fuel; - liquid explosives.

LQtest Device Detects as DANGEROUS:
Combustive-lubricating materials,oil products
Alcohol containing liquids (ethylene above 60%)
Liquid explosives and ingredients

LQtest Device Defines asSAFE:
Beverages (below 60%)
Liquid household chemicals
Perfumes, cosmetics (alcohol content below 60%)

Test Results on Liquid Explosives and ingredients:
Detects as dangerous:
Liquid nitroethers (nitroglycol, diethyleneglycol dinitrate, iso-propylnitrate)
Liquid explosives (mixtures based on caoutchouk and nitroethers)
Nitroolefins, nitromethanes
Active bonding agents of solid propellants (azidoethanol, glycidyl nitrate, glycyl dinitrate, glycidylazide polymer, ternary mixture based on nitrazolefin derivatives)
Mixture of mineral oil, ammonium nitrate, emulsifier and water (a substrate for emulsive explosives)
Mononitrotoluenes
Halogen containing solvents, such as carbon tetrachloride, ethylene dibromide, propylene dibromide.

LQtest can help solving a number of unaddressed actual problems:
Control of baggage transportation of dangerous liquids
Screening and control of beverages entering the airport clean area, as well as those included in onboard meals and coming to Duty Free shops
Screening of dangerous liquids inside small containers (below 100 ml)

LQtest can help solving a number of unaddressed actual problems:
The use of LQtest in the inspection practice will allow fast and reliable detection of hazardous liquids without causing inconveniences for the passengers

LQtest: 12+ month of effective inspection in major Russian airports
Russian airports:
Moscow, Novosibirsk, Saint-Petersburg, Mineralnie Vody, others: tens of thousands containers with liquids were inspected during 2008.

Our proposals for 20th meeting of Aviation Security Panel
To study inspection practice of LQtest devices in Russian airports.
To test on practice LQtest devices in different airports world wide under supervision of relevant bodies.
To develop Standard Operation Procedures and other legal documents for inspection of sealed containers with liquids in airports.
