Abstract
An apparatus for airborne particle sorting is provided comprising a charging system adapted for applying an electrostatic charge to the particles, such that particles of at least a first group are deflected to a greater extent than particles of a second group are deflected. A focusing system is adapted for electrostatically focusing substantially at least the particles of the first group into a focused stream that is narrower than the input air stream. A deposition system is adapted for substantially depositing the particles of the first group from the focused stream upon a target surface, where the target surface may be transported to an analysis system capable of analyzing the particles deposited thereon.
