Title (EN) METHOD AND APPARATUS FOR INCREASING THE SIZE OF SMALL PARTICLES
(FR) PROCEDE ET APPAREIL POUR AUGMENTER LA TAILLE DE PETITES PARTICULES
Abstract: front page image
(EN)Method and apparatus for increasing the size of small particles for a condensation particle counter (20), in which method a particle containing aerosol flow is divided into a sample flow and a sheath flow. The sheath flow is filtered, saturated with vapor and formed to a vortex flow in saturator (21) which vortex-flow continues in condenser (22). The sample flow is introduced to the centre of the vortex flow of the saturated sheath flow in condenser (22) for causing the vapor in the saturated sheath flow to condense on the particles in the sample flow thus increasing the size of the particles.
(FR)L'invention porte sur un procédé et sur un appareil permettant d'augmenter la taille de petites particules dans un compteur de particules de condensation (20), procédé selon lequel un écoulement aérosol contenant des particules est divisé en un écoulement d'échantillon et un écoulement en gaine. L'écoulement en gaine est filtré, saturé par la vapeur et transformé en un écoulement tourbillonnaire dans un saturateur (21), cet écoulement tourbillonnaire continuant dans un condensateur (22). L'écoulement d'échantillon est introduit au centre de l'écoulement tourbillonnaire de l'écoulement en gaine saturé du condensateur (22) de façon à provoquer la condensation de la vapeur de l'écoulement en gaine saturé sur les particules de l'écoulement d'échantillon, ce qui permet d'augmenter la taille des particules.
