Abstract

A new concept for effective sampling and detecting HME powder traces is described. The collection is based on the particles mobility under rotation into an accumulation collector unit, followed by sequential transfer to the electrochemical detection system where surface washing yields a higher concentration at room temperature. The electrochemical detection of the peroxide explosives is based on photochemical degradation or acid treatment resulting in hydrogen peroxide which is sensed by a Prussian-blue (PB) modified strip electrode at a low potential. Nitrates such as Urea Nitrate are detected using unique reactions which generate one product which has a specific electrochemical signature. Nitroaromatics, nitramines and nitroesters are detected. The new "Add and Detect" procedure is operator independent and is the safest as the operator.
