Abstract

Dispositif impacteur pour la séparation des particules d'un aérosol en classes granulométriques. Le dispositif comprend une première buse convergente à fente rectangulaire pour l'écoulement de l'air filtré et une seconde buse convergente avec une fente rectangulaire pour l'écoulement de l'aérosol à analyser, la fente d'écoulement d'aérosol étant décalée par rapport à celle d'écoulement d'air filtré et le courant sortant de cette dernière étant dirigé sur une plaque plane munie d'une fenêtre filtrante L'invention est applicable notamment à l'hygiène industrielle, par exemple en cas de risque de contamination radioactive.
