Abstract
A method and apparatus for the extraction of particles from surfaces is disclosed. A preferred method comprises the steps of (1) adjusting the temperature and humidity of an air supply to provide an adjusted air supply, (2) directing a blast from the adjusted air supply to a surface bearing particles, so as to produce a deflected blast that comprises some of the particles from the surface, (3) collecting the deflected blast and particles, and (4) directing the deflected blast and particles towards an analyzer. A preferred apparatus includes an air adjuster and a probe comprising an adjusted air supply passage, an adjusted air aperture, a deflected air aperture, and a deflected air passage, wherein the air adjuster is adapted to provide a flow of adjusted air to the adjusted air supply passage and the adjusted air aperture.
