Abstract (en)

[origin: EP2108456A1] The device has a cone shaped droplet recuperator (7) including a netted lateral wall (2) convergent towards an outflow port (9) to permit droplets attracted towards the wall to be poured towards the port. A discharge electrode (1) e.g. polarized wire, is mounted inside the recuperator. The wall defines a counter electrode on the electrode (1) to attract the droplets collecting submicron particles e.g. pathogenics, carried by exhaled breath towards the wall, and has conductive strips (34) made of metal. The recuperator and a cooling system (16) define an electrostatic precipitator. The wall has a grooved inner side (4) that is made hydrophilic by surface treatment i.e. silicon dioxide deposition. An independent claim is also included for an extracted particle analyzing system comprising an extracted particle collecting device.
