Abstract
A device for collecting particles in air comprising a collecting chamber (4), a capillary tube (12) whereof one end (12.1) terminates in the chamber (4), a collecting electrode, the capillary tube (12) containing polarisable liquid. Sufficient difference in voltage is applied between the liquid and the collecting electrode (16) for a corona effect between the drop of liquid at the end of the capillary tube (12) and the collecting electrode (12) and the spraying of the drop (20) by electrospray. The corona discharge causes flow of air through the collecting chamber (4) and the electrospray ensures wetting of the collecting electrode (16).
