Abstract
A method for purifying particles generates charged particles from a sample, measures at least at least one of masses, charge magnitudes and mobilities of the generated charged particles, and selectively passes to a particle collection target each of the measured charged particles having at least one of (a) a measured mass equal to a selected mass or within a selected range of particle masses, (b) a measured charge magnitude equal to a selected charge magnitude or within a selected range of charge magnitudes, (c) a mass-to-charge ratio equal to a selected mass-to-charge ratio or within a selected range of mass-to-charge ratios, and (d) a measured mobility equal to a selected mobility or within a selected range of mobilities. In some embodiments, the collected particles may be harvested and amplified.
