Title (EN) PARTICLE PROCESSING
(FR) TRAITEMENT DE PARTICULES
Abstract: front page image
(EN)The invention concerns a method for processing magnetic particles, which selectively interact with a substance present in a liquid medium. The particles are collected with a probe (2) comprising a hollow shield (4) and a probe magnet (3) moveable up and down. The lower end of the probe with the collected particles is placed on a release location (7) of a plate (6), below which release location there is a release magnet (8). The surface of the release location is dry or has a liquid film or a drop on it. In accordance with the invention, very high concentration ratios can be achieved.
(FR)L'invention concerne un procédé destiné à traiter des particules magnétiques, qui entrent sélectivement en interaction avec une substance présente dans un milieu liquide. Les particules sont collectées à l'aide d'une sonde (2) comprenant une gaine creuse (4) et un aimant (3) de sonde pouvant monter et descendre. L'extrémité inférieure de la sonde comportant les particules collectées est placée sur un emplacement amovible (7) d'une plaque (6), un aimant amovible (8) se trouvant sous l'emplacement amovible. La surface de l'emplacement amovible est sèche ou un film liquide ou une goutte se trouve sur celle-ci. Conformément à l'invention, on peut obtenir des rapports de concentration très élevés.
