Abstract

See full text

The invention is essentially a sequential (“DMA”) apparatus using a novel arrangement of at least three electrodes and at least two block electrodes to produce a DMA apparatus having at least two sequential DMA regions between pairs of adjacent electrode walls within the same housing. This apparatus is used to improve the transfer of particles into the subsequent DMA region without a vacuum or pump, and to improve the separation of target particles from non-target particles and concentration and collection of the target particles.
