Abstract

A method and a device for quick neutralization of a created electrostatic field formed by a multitude of basically charged particles includes a medication powder ( ) deposited onto a defined target area ( ) of a substrate member ( ) in the course of a dose forming process. A charge generator emits charges, which are directed towards the target area of the substrate member such that the electric field created by the accumulated charges from the deposited particles is neutralized by the added charges. Various elements may be used to generate neutralizing charges, but an ion source ( ) is most efficient in achieving neutralization of the dose charge and the substrate. The source may be applied so that the dose ( ) and the target area ( ) are exposed to the emitted charges during the entire or part of the dose forming process.
