Device for the separation of magnetic or magnetizable microparticles consist of a suspension mittelshochgradienten-magnetic separation

摘要

The invention relates to a device for the separation of magnetic or magnetizable microparticles consist of a suspension (5) by means of high gradient magnetic separation. For this purpose, the apparatus has a separator (12), the housing (13), a separation chamber (1), which surrounds a suspension (5) in a predetermined flow direction (5 '') is capable of flowing. In the separation chamber (1) is a magnetic or magnetizable separating matrix (2), the more in the free lateral distance from each other surface elements (3), which, in this way, flow chambers (6) for the suspension (5) in the form of. The suspension (5), via a supply line (26) and an outlet (30) into and out of the flow spaces (6). In order to the loading state of the separating matrix (2) with microparticles in the separation chamber (1) and based thereon, a prediction about the probability of a detachment of microparticles of the separating matrix (2) to be able to meet, the invention provides for the use of an optical measuring device (7) and an illumination system (9) in front of, for the determination of the size of the clearance distance between the surface elements (3), the optical sightlines (8) of the optical measuring device (7) in the flow spaces (6) and the illumination system (9) includes at least one light source whose light (10) in the flow spaces (6) is emitted.
