Abstract
A separation device with a transparent separation chamber, whereby a direct light source illuminates the components to be separated and the individual components reflect the light intensity as a function of their individual coloring (brightness) via optics onto a linear group of photodetectors. The signals received by the detectors are forwarded to a computing unit in which they are processed. A regulating unit, which operates very precisely due to the accuracy and the high speed of the receiver and computing unit, is controlled according to a program and thus assures optimum separation performance of the separation device.
Claims15
A device for separation of media into their components through density centrifugation, comprising:
- a separation chamber;
- means for detection and adjustment of the phase boundary between at least two optically differentiable fractions of the medium;
- a light source which illuminates the separation chamber in a region of the phase boundaries which are adjusting themselves;
- a light receiving arrangement and optics which reproduce a specific section of the region on the light receiving arrangement, which responds to different light signals according to optical differences in the fractions;
- and
- an electrical control circuit means connected downstream from the light receiving arrangement to trigger control signals, wherein the light source and the light receiving arrangement are disposed with the optics such that the light receiving arrangement receives light signals corresponding to the brightness of the components and the control circuit is designed such that control signals can be triggered based on the differences in brightness.
