ABSTRACT:
The electrostatic selector of aerosol particles of an atmosphere has a first (18) and a second (20) spaced, parallel, coaxial conductive disks between which is established an electrical field, an annular slot (22) made in the first disk in order to communicate with the atmosphere to be examined, a central intake (26) for bringing about a circulation from the periphery of the disks of a stable, centripetal, laminar filtered air flow, the second disk (20) having a central extraction orifice (28).
