    Abstract: This invention provides an apparatus and method for the complete fractionation of submicron particles according to size by capillary hydrodynamic fractionation. This objective is achieved by using small diameter capillaries (18); introducing a minor fraction of a liquid dispersion of particles to be separated into at least one capillary fraction; passing the minor fraction through the capillary (18); and, at the exit of the capillary (18), diluting the minor fraction with the same liquid as is carrying the fractionated sample. These modifications in the flow patterns are essential to the use of capillaries (18) with diameters smaller than 60 microns. This invention is especially adapted for rapid analytical separation of not only rigid colloidal particles but also of soft latexes.

    Abstract: L'invention concerne un appareil et un procédé de fractionnement complet de particules submicroniques d'après la taille par fractionnement hydrodynamique capillaire. Cet objectif est atteint en utilisant des capillaires de petit diamètre (18), en introduisant une petite fraction d'une dispersion liquide de particules à séparer en au moins une fraction capillaire, en faisant passer la petite fraction au travers du capillaire (18), et, à la sortie du capillaire (18), en diluant la petite fraction avec le même liquide que porte l'échantillon fractionné. Ces modifications dans les configurations d'écoulement sont essentielles à l'utilisation de capillaires (18) ayant des diamètres plus petits que 60 microns. Cette invention est spécialement adaptée à la séparation analytique rapide non seulement de particules colloïdales rigides mais également de latex souple.
