A differential mobility analyzer and analysis method electromobility

摘要

A differential mobility analyzer and analysis method electromobility # analyzer comprising:. Duct (7) leading to the passage of a flow (F), inlet (1) secondary flow sample with neutral particles (L) to the duct (7) main, means (4, 5) for generating a field (E) power in the region (C) classification means (3) for discriminating the particles (P) according to their electrical mobility, means (6) for loading particles in the region (C) classification is achieved the secondary flow (L) after entering the main duct (7). This prevents the neutralization of particles of different sign by collisions with each other or with the walls and growth in size by reactions with the environment. The method comprises establishing a main flow (F), injecting a secondary flow (L) and that the latter is adhered to the wall through which is injected, passing both through a field (E), in charging the particles of the secondary flow (L ) and sweeping an electric field to discriminate charged particles according to their electrical mobility.
