Title (EN) METHOD AND APPARATUS FOR AIRBORNE PARTICLE CONCENTRATION AND COLLECTION
(FR) PROCEDE ET DISPOSITIF DESTINES A LA CONCENTRATION ET A LA RECUPERATION DE PARTICULES AERIENNES
Abstract:
(EN) Embodiments of an apparatus for concentrating and collecting airborne particles (e.g., biological aerosols) from an air sample include an inlet adapted for receiving the air sample (e.g., from an external or surrounding environment), a first diffuser coupled to the inlet and adapted to concentrate the airborne particles into a particle flow, and at least a second diffuser coupled to the first diffuser in a cascaded configuration and adapted to further concentrate the particle flow.
(FR) Des modes de réalisation de la présente invention concernent un dispositif destiné à la concentration et à la récupération de particules aériennes (aérosols biologiques, par exemple) à partir d'un échantillon d'air. Ce dispositif comprend une entrée conçue pour recevoir l'échantillon d'air (provenant d'un milieu externe ou ambiant, par exemple), un premier diffuseur couplé à l'entrée et conçu pour concentrer les particules aériennes pour former un flux de particules, et au moins un second diffuseur couplé au premier diffuseur, selon une configuration en cascade, conçu pour concentrer davantage le flux de particules.
