<p>The subject of the invention is a method for minimising Coulombic losses in impactors and an impactor, in which the Coulombic losses have been minimised. The method according to the invention is based on restricting the force effect of the charges accumulated in impactor's insulators (24) on the charged particles. This restriction of the force effect can be realized, for example, by placing an electricity conductive surface (70) between the insulator (24) and the flow (21), or by forming an insulator (24) so that the force effect is minimised.</p> |
