Abstract
An explosive and narcotics detection system detects the presence of trace particles of those materials that are adhering to surfaces. The particles are removed from the surface, transported and collected in a particle collection medium, and then provided to detection instrument. Narcotics and explosive particles are often bound tenaciously to the surface, and simple techniques, such as blowing air, will either remove only the largest particles or none at all. Techniques for the removal of narcotics and explosives particles are described which utilize an aerosol mixture of aerosol particles in a gas stream to impact and more efficiently remove the target narcotics and explosives particles from the surface.
