Abstract
(EN)
This centrifugal sedimentation-type particle size distribution measurement device is provided with: a cell holding body 31 which holds a measurement cell 2 for receiving a sample to be measured and a dispersion medium and a reference cell 6 for receiving a reference sample and is rotated by a motor 322; and a cell discrimination mechanism 7 for discriminating the cells 2, 6 passing through a predetermined rotation position using magnetic force or electrostatic capacity.
(FR)
La présente invention concerne un dispositif de mesure de distribution de taille de particules de type à sédimentation centrifuge qui est pourvu de : un corps de maintien de cellule (31) qui contient une cellule de mesure (2) pour recevoir un échantillon à mesurer et un milieu de dispersion et une cellule de référence (6) pour recevoir un échantillon de référence et est mis en rotation par un moteur (322) ; et un mécanisme de discrimination cellulaire (7) pour discriminer les cellules (2, 6) passant à travers une position de rotation prédéterminée à l'aide d'une force magnétique ou d'une capacité électrostatique.
(JA)
