METHOD AND APPARATUS FOR AIRBORNE PARTICLE SORTING

摘要

An apparatus (100) for airborne particle sorting is provided. The apparatus includes a charging system (104) 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 (106) 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 (108) is adapted for sustantially 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 (112) capable of analyzing the particles deposited thereon.
