Feasibility study regarding direct analysis of explosives

FOI can identify and quantify most of the, from a threat perspective relevant, explosives and energetic salts. FOI have developed a new application based on proven sampling and analysis techniques, where these substances can be selectively identified with high certainty in less than one minute. The idea with the new application has been studied in a sex month project to evaluate its functionality and potential. It was funded by the Armed Forces for research and technical development purposes. The methodology can be used for online, real-time sampling and analysis with the same quality as with an experienced chemist and high tech, expensive and sensitive analytical instrument. The concept could be ideal for security screening of vehicles, cargo and people in a check point or at an entrance of an area or facility. The risk of false alarms is minimal, since sampled substances are weight on an atomic level for specific and selective identification. False alarms are also prevented by single-use components for sampling, enabling explosives residues causing a memory effect. The method is optimal for stationary use, but the unit is mobile and can be used in field operational settings as well. Remote detection is possible, if sampling and analyses are performed in two separate steps. The sample can also be divided to get both instant analysis and a separate forensic proof and/or external validation opportunity. In field use of the equipment demands a power supply and air conditioning. Sampling is done by the use of chargeable units and it is possible to collect samples and identify explosives, energetic salts and other target substances as in example narcotics, in an operational setting. Possible further development is to modify unmanned vehicles for remote sampling purposes in out of reach areas or hot spots. The modification could also include the ability to take water samples. The new concept also have the ability to identify a wide range of other substances, in example drugs or environmental toxins. The wide range of possible applications makes this interesting also for civilian authorities as the police or customs, or for environmental surveillances use. The opportunity to expand the areas of use of already existing instruments will make it interesting for industries to invest in further development. This will help bring a new solution useful for the Armed Forces, to the market.
