Abstract
A device for picking and transporting nano-objects present in an aerosol for analyzing includes a porous sampling filter configured to trap the nano-objects. The device also includes a cassette having means for holding the filter in a cavity within the cassette, an inlet orifice configured to allow aspirated aerosol to pass through, and an outlet orifice configured to pass the filtered aerosol, rid of the nano-objects trapped upstream of the inlet orifice of the cassette. A module of the device is configured to collect, by inertial impaction, the particles of a size above a threshold value and to allow aerosol containing particles of a size smaller than the threshold value to pass. The module is further configured to reduce, during picking, emission noise of the aspiration means of the picking device on which the cassette is fixed.
